flash/nor: Add support for TI CC26xx/CC13xx flash

Added cc26xx flash driver to support the TI CC26xx and CC13xx
microcontrollers. Driver is capable of determining which MCU
is connected and configures itself accordingly. Added config
files for four specific variants: CC26x0, CC13x0, CC26x2, and
CC13x2.

Note that the flash loader code is based on the sources used
to support flash in Code Composer Studio and Uniflash from TI.

Removed cc26xx.cfg file made obsolete by this patch.
