Both the error output in function decompile_section() and the
definition of GPIO_BANK_MAX in script.h suffered from an "off
by one" logic. The bank numbering in the .bin is based on 1,
so it should be added to ('A' - 1) for human-readable output,
and the maximum number corresponding to 'N' is 14.
This became apparent when trying to translate a fex2bin-compiled
a80_optimus_board.bin back to its original .fex equivalent.
