[PATCH V3] drm/radeon/kms/r600+: use voltage from requested clock mode

[Rafał Miłecki]

This fixes FDO bug #28375, it's kind of regression, so quite important to have
it for .35.

V2: Fix on RV770+ as well. All other chipsets have only one clock mode per
state.

V3: I'm out of luck today. Grepped for voltage in r*.c and missed evergreen.
