keypad boot init overhaul: handle initially held-down keys
This change fixes two previous behavioural defects:
1) On Compal phones, the PWR key had to be released before the boot
sequence would proceed at all - it was stuck in an endless IRQ loop
at the point of Nucleus enabling interrupts, before anything else.
2) On both Compal and sane platforms including Luna, if some regular
non-PWR key was held down at boot time, the boot sequence would
proceed and complete normally, but all non-PWR keypad buttons would
be dead for the remainder of that boot cycle.
The fix is a generic solution - no Compal-specific hack ended up being
needed for the special case of their idiotic PWON-to-ROW4 hw wiring.
