soc/intel/meteorlake: Log CSE RO write protection info for MTL

The patch logs CSE RO's write protection information for Meteor Lake
platform. As part of write protection information, coreboot logs status
on CSE RO write protection and range. Also, logs error message if EOM
is disabled, and write protection for CSE RO is not enabled.

Port of commit abe0d810f009 ("soc/intel/alderlake: Log CSE RO write
protection info for ADL").

BUG=none
TEST=Verify the write protection details on google/rex.

Excerpt from google/rex coreboot log:
[DEBUG]  ME: WP for RO is enabled        : YES
[DEBUG]  ME: RO write protection scope - Start=0x4000, End=0x396FFF
