altos/lpc: Give up on interrupt-driven SPI driver
There are just too many limitations in when interrupts are delivered
to make them useful. Instead, just drive the SPI directly with the
CPU. At higher spi speeds (6Mhz or more), it's probably faster to do
it this way anyways.

altosuilib: EEProm download from TeleGPS doesn't have states
As TeleGPS doesn't have flight states, the EEProm download progress
bar shouldn't show 'state invalid', and it should use a different
scale for each block.
Fix this by having AltosConfigData know which devices have state based
on their log format, then mark the progress bar state limits as
'invalid/invalid' instead of 'boost/landed'. Then have the progress
bar use that to set a more reasonable scale for each block.

altos: Fix up telemetry delay computations
With RDF, APRS and telemetry all being sent at varying rates,
computing when to send the next radio data is not as simple as sending
telemetry and then figuring out whether to send RDF and/or APRS.
Fix this by computing times for the next telemetry/rdf/aprs packet,
and only sending each when that time has passed. Compute the delay
until the next radio activity as the minimum time to any transmission.
This also adds code to the config bits to reset the radio times
whenever something changes that might affect which radio data to send
next.
