target: Rework 'set' variable of break-/watchpoints
The 'set' variable name suggests a boolean data type which determines
whether a breakpoint (or watchpoint) is active. However, it is also
used to store the number of the breakpoint.
This encoding leads to inconsistent value assignments: boolean and
integer values are mixed. Also, associated hardware comparator
numbers, which are usually numbered from 0, cannot be used directly.
An additional offset is required to store the comparator numbers.
In order to make the code more readable and the value assignment more
consistent, change the variable name to 'is_set', its data type to 'bool'
and introduce a dedicated variable for the break-/watchpoint
number.
In order to make the review easier, the data types of various related
variables (e.g. number of breakpoints) are not changed.
While at it, fix a few coding style issues.

target: ls1088a: Add service processor
Normally the service processor is not necessary for debugging. However,
if you are using the hard-coded RCW or your boot source is otherwise
corrupt, then the general purpose processors will never be released from
hold-off. This will cause GDB to become confused if it tries to attach,
since they will appear to be running arm32 processors. To deal with
this, we can release the CPUs manually with the BRRL register. This
register cannot be written to from the axi target, so we need to do it
from the service processor target. This involves halting the service
processor, modifying the register, and then resuming it again. We try
and determine what state the service processor was in to avoid resuming
it if it was already halted.
The reset vector for the general purpose processors is determined by the
boot logation pointer registers in the device configuration unit.
Normally these are set using pre-boot initialization commands, but if
they are not set then they default to 0. This will cause the CPU to
almost immediately hit an illegal instruction. This is fine because we
will almost certainly want to attach to the processor and load a program
anyway.
I considered adding this as an event handler for either gdb-attach or
reset-init. However, this command shouldn't be necessary most of the
time, and so I don't think we should run it automatically.

the existing target event mechanism, to implement a general-purpose Tcl

- The user configures a Tcl command as a callback for one of the newly

- The target can make a semihosting call with <opnum>, passing optional

flash/nor/efr32: fixed lockbits and user data
Changed flash driver to support writing to the user data page, as well as to any portion of the lockbits page above 512 bytes (the amount used for the actual page lock words). The top part of the lockbits page is used on at least the EFR32xG1 chips for the SiLabs bootloader encryption keys.
As presented to the user, the lockbits page is the same size as the other pages, but any attempt to write to its low 512 bytes is an error. To enforce this, efr32x_write is renamed to efm32x_priv_write and a wrapper function is provided in its place. If the user erases the lockbits page, the driver rewrites the cached lock words after the erase. When the driver erases the lockbits page in order to update the lock words, it first takes a copy of anything stored in the top part of the page, and re-programs it after the erase operation.
There are now multiple instances of flash_bank for each target, and the flash_bank instances must share their cached lock words to operate as intended. Therefore, when a bank is created, the global flash bank list is used to find any other banks that share the same target. Since some banks in the global list are invalid at the time free_driver_priv is called, reference counting is used to decide when to free driver_priv.
To avoid the need to find the lockbits flash_bank from another flash_bank, efm32x_priv_write and efm32x_erase_page now take an absolute address.
There didn't seem to be any reason to prohibit unprotecting individual flash pages, so that limitation is removed from efm32x_protect().
This addresses ticket #185.

adi_v5_swd: add jtag-to-swd through dormant
ARM IHI 0031A does not support SWJ-DP, so no switch between JTAG
and SWD is considered.
ARM IHI 0031B is not publicly available and it's reported as
"Confidential Beta" in the history list in following doc versions.
From ARM IHI 0031C the direct switch between JTAG and SWD is
already deprecated in favor of passing through dormant mode. With
no access to IHI 0031B we haven't info if any device strictly
requires the direct switch.
OpenOCD implements only the deprecated direct switch, so changing
it could cause regression on devices that do not implement dormant
mode.
Plus, not all the adapters support dormant mode.
Nevertheless there are already target devices that only allow
entering in SWD by passing through dormant.
Let the code try both method, alternating one tentative with the
deprecated legacy direct switch, then another tentative passing
through dormant, and repeat till timeout.
This would work on any device that don't support dormant, on new
devices that require switch through dormant and will work with
adapters that don't support dormant.
