[Intel-gfx] [PATCH] drm/i915: Remove CONFIG_PM dependency from RC6.

[Rodrigo Vivi <rodrigo.vivi@intel.com>]

RC6 is a sleep state that doesn't depend on the cpu sleep,
or any of the APM or ACPI or anything related to the
CONFIG_PM.

A long time ago we have removed the module parameter
that allows the RC6 disablement. We want that feature enabled
everywhere. However, for some reason this CONFIG_PM was long
forgotten behind.

If we end up needing knobs to disable RC6 we should create
individual ones, rather than relying on this master one.
