hp/pavilion_m6_1035dx/cmos.layout: Remove unused options

Some of the options in cmos.layout date back to the K8 days, and have
not been used anywhere else, but K8. This makes nvramtool expose a
very confusing set of options, most of which have no effect. Clean up
the layout before it gets forked again.

TEST: Booted linux, and checked 'nvramtool -a' output.
