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.

  PURPOSE : Decoding of the GSM Type 5TLV element. This element
            consists of a 8 bit T component a
            8 or 16 Bit L component and a V component wich
            length depends on the value of the L component.
            If the length is in the range 0x00-0x7f the L component
            consist of one byte. For bigger length 0x80-0xff the
            L component consists of two bytes. The first byte is
            tied to 0x81 and the second byte contains a value in the
            range 0x80 to 0xff.
