arm_adi_v5: add support for display Class 0x9 ROM tables

arm_adi_v5: add support for display Class 0x9 ROM tables

ADI v5.1 and v6.0 permit the definition of CoreSight components (class 9
ROM entries).

dap_rom_display() is refactored a bit such that we always end up with
attempting to parse the ROM contents using the appropriate upper limit
for class 1 and 9 ROM types.
