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.

When TI's original version of small B&W UI firmware boots or shuts down, the splash screen it displays consists of a 56x38 pixel B&W TI logo centered in the middle of the LCD. (Back when this code was owned by Condat rather than TI, this splash screen was an animated Condat logo of approximately the same size - it is still present in the code, conditioned out.) Because we are FreeCalypso and not TI or Condat, we need our own logo or at least our own splash screen to replace those other company logos. A bona fide FreeCalypso logo does not exist yet as of this writing (2021-03), and while we (Falconia family that owns FC) do have some logo ideas in the works, the 96x64 pixel B&W (1bpp) framebuffer in the FreeCalypso Lite config is far too limited compared to other media - hence we are currently going for a simple splash screen that merely consists of the words "FreeCalypso Lite". The current version of our minimal-effort splash screen is 80x30 pixels, to be centered in the middle of the 96x64 pixel LCD. The bitmap drawing is given in bwsplash.pbm, which is a Plain PBM file, making the pixel image directly viewable and editable in vi. The tools in this directory compile it into hex bytes for inclusion in C source, and the finished artifact goes into src/ui/bmi/mmiIcons.c, fc_splash_screen_smallbw[] char array. The coordinates for positioning this bitmap within the full 96x64 pixel framebuffer are given in src/ui/bmi/mmiResources.h - look for WELCOME_ANI_POS_X and WELCOME_ANI_POS_Y definitions. The present splash screen is strictly a minimal-effort job with absolutely no quality claims of any kind. If someone is more graphically talented than I am, or has more time to invest into drawing a prettier splash screen, suggestions for improvement are always welcome.
