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.
