 Setting CONFIG_SIMPLELINK_HOST_DRIVER=y builds the SimpleLink Host

+TI provides the driver library functions burned into ROM at the factory,
+or updated via a service pack patch, thus saving application code space.
+
+Calling driverlib APIs prefixed by "MAP_" will vector to those functions
+already existing in ROM.
+
+After setting CONFIG_HAS_MSP432P4XXSDK=y in Kconfig, most of the
+peripheral driver library functions will be accessible from ROM.
