[Intel-gfx] [PATCH 2/7] drm/i915: Change VLV GEN6_RP_DOWN_TIMEOUT value to decimal

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We use decimal for all the other RP magic values, so change
GEN6_RP_DOWN_TIMEOUT to decimal as well. Also change the order
of the register writes to match the BIOS spec for easier verification.
