flash/nor: add support for TI MSP432 devices

Browse Source 
Added msp432 flash driver to support the TI MSP432P4x and
MSP432E4x microcontrollers. Implemented the flash algo
helper as used in the TI debug and flash tools. This
implemention supports the MSP432E4, Falcon, and Falcon 2M
variants. The flash driver automatically detects the
connected variant and configures itself appropriately.
Added command to mass erase device for consistency with
TI tools and added command to unlock the protected BSL
region.

Tested using MSP432E401Y, MSP432P401R, and MSP432P4111
LaunchPads.
Tested with embedded XDS110 debug probe in CMSIS-DAP
mode and with external SEGGER J-Link probe.

Removed ti_msp432p4xx.cfg file made obsolete by this
patch.

@deffn {Flash Driver} msp432
All versions of the SimpleLink MSP432 microcontrollers from Texas
Instruments include internal flash. The msp432 flash driver automatically
recognizes the specific version's flash parameters and autoconfigures itself.
Main program flash (starting at address 0) is flash bank 0. Information flash
region on MSP432P4 versions (starting at address 0x200000) is flash bank 1.
@example
flash bank $_FLASHNAME msp432 0 0 0 0 $_TARGETNAME
@end example
@deffn Command {msp432 mass_erase} [main|all]
Performs a complete erase of flash. By default, @command{mass_erase} will erase
only the main program flash.
On MSP432P4 versions, using @command{mass_erase all} will erase both the
main program and information flash regions. To also erase the BSL in information
flash, the user must first use the @command{bsl} command.
@end deffn
@deffn Command {msp432 bsl} [unlock|lock]
On MSP432P4 versions, @command{bsl} unlocks and locks the bootstrap loader (BSL)
region in information flash so that flash commands can erase or write the BSL.
Leave the BSL locked to prevent accidentally corrupting the bootstrap loader.
To erase and program the BSL:
@example
msp432 bsl unlock
flash erase_address 0x202000 0x2000
flash write_image bsl.bin 0x202000
msp432 bsl lock
@end example

@deffn {Flash Driver} niietcm4
This drivers handles the integrated NOR flash on NIIET Cortex-M4
based controllers. Flash size and sector layout are auto-configured by the driver.
