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.
