cfi_flash: A bit of cleanup and code simplification

Hi,

following are a few patches with minor code clean-up and simplification for the cfi_flash driver. Especially the usage of CONFIG_SYS_MAX_FLASH_BANKS_DETECT to support dynamic flash bank number detection is reworked a bit. Additionally, now the flash base address list can be dynamically changed if needed as well.

Here the shortlog:

Stefan Roese (4):
cfi_flash: Simplify flash_get_info()
cfi_flash: Add weak default for cfi_flash_bank_addr()
cfi_flash: Simplify dynamic flash bank number detection
cfi_flash: Remove uneccessary #ifdef CONFIG_SYS_MAX_FLASH_BANKS_DETECT

As you can see, these patches touch non-cfi related files too. If nobody objects, I'll collect these patches in my cfi-flash repository for the next merge window.

Cheers,
Stefan
