mb/**/cmos.layout: Remove crusty comments

Most of these comments have been copy-pasted or serve no purpose other
than to eventually turn into misleading info. While the description of
the first 120 bits of CMOS could be useful, it should instead be added
to the documentation for the CMOS option infrastructure, or /dev/null.
Moreover, trim down newlines to no more than two consecutive newlines.
