cfi_flash: Simplify dynamic flash bank number detection
This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By
moving these optional variables and defines into the common code, board
specific code is minimized. Currently only the following board use
this feature:
APC405, IDS8247, TQM834x
And IDS8247 doesn't seem to really need this feature, since its not
updating the bank number variable at all. So this patch removes the
definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port.
This new framework will be used by the upcoming lwmon5 update as well.
