flash/nor: update CC26xx/CC13xx support 

Added fixes found in additional code reviews.

Remove inappropriate use of bank_number field and updated
documentation to reflect the change.

Restored functionality to cc2538.cfg file because previous
change removed the cc26xx.cfg file because the flash support
changes made it obsolete. Rolled the previous cc26xx.cfg
file into cc2538.cfg and updated it to work with other
recent changes.  Tested using a SmartRF06 Evaluation
board with embedded XDS100v3 and external XDs110.

All versions of the SimpleLink CC13xx and CC26xx microcontrollers from Texas
Instruments include internal flash. The cc26xx flash driver supports both the
CC13xx and CC26xx family of devices. The driver automatically recognizes the
specific version's flash parameters and autoconfigures itself. Flash bank 0
