sanitycheck: Add support for TI XDS110 to --generate-hardware-map

Add support for boards that utilize the TI XDS110 like the CC3220SF,
CC3235SF, CC1352R1 and CC26x2R1 LaunchXL boards.  The XDS110 can expose
multiple serial endpoints one for the uart device, but another for a
trace buffer.  We assume that endpoint 0 will be the UART device.
