mb/intel/d510mo: Configure clockgen 

Configuring the clockgen like vendor bios fixes the issue where the
display wobbles from left to right on the analog VGA output.

Note: This seems to be common issue/requirement on Intel devices from
that generation (also happens on dg43gt).

TESTED on Intel D510MO.
