soc/intel/meteorlake: Enable eSOL without 64-bit support

This change allows eSOL to be enabled on production Meteor Lake silicon
even when 64-bit support is not present. eSOL support is still TBD for
64-bit FSP hence, skip adding this support for 64-bit build.

TEST=Able to build and boot google/rex64 w/o eSOL.
