mb/asrock/b75pro3-m: Add CMOS layout/defaults and vbt.bin

The ASRock B75 Pro3-M port was lacking a cmos.default and cmos.layout,
which means nvramtool could not be used to change any nvram values, and
the defaults were always being used.

I have "borrowed" the files from the similar h77pro4-m port, which
work fine for the b75pro3-m. I can now adjust things like gfx_uma_size
and power_on_after_fail, which are quite useful to be able to modify.

Additionally, this board did not have a data.vbt, so I extracted
vbt.bin from the VGABIOS and added it.
