ATOMBIOS: Add support for DynamicClocks option
This patch adds support for dynamic clock gating and static
power management using the atom command tables. In some cases
the bios may already set this up during post, so YMMV.
I was only able to test on desktop cards, so I haven't tested
to see how much (if any) power this saves or how it affects the
thermal footprint.
