[Intel-gfx] [PATCH 1/8] drm/i915/dmc: simplify intel_dmc_load_program() conditions

[Jani Nikula]

intel_dmc_load_program() is only ever called when
intel_dmc_has_payload() is true. Move the condition within
intel_dmc_load_program() to let it be called directly.

Also note that intel_dmc_has_payload() will always return false when
HAS_DMC() is false. Remove the redundant check.
