soc/intel/jasperlake: Add function to display ME firmware status info
Add function to display ME Host Firmware Status registers. Make use of print_me_fw_version() from CSE lib to print ME firmware version information. Add manufacturing mode field in HFSTS1 register for JSL in place of, spi_protection_mode in TGL. BUG=None BRANCH=None TEST=Build and boot jslrvp. In coreboot logs, ME info can be seen.
