util/mma: Add MMA scripts for setup and getting results

mma_setup_test.sh is used to set MMA test name and MMA test config
name. After executing this script user needs to reboot the system and
FSP/coreboot would execute the selected MMA test. FSP and coreboot needs
to be built with MMA support.

mma_get_result.sh will get the raw MMA results from cbtable and save it
to bin file.
