[Intel-gfx] [PATCH v2 1/2] drm/i915/cdclk: turn around i915_drv.h and intel_cdclk.h dependency

[Jani Nikula <jani.nikula@intel.com>]

intel_cdclk.h only needs i915_drv.h for struct intel_cdclk_config. Move
the definition to intel_cdclk.h and turn the includes around to avoid
including i915_drv.h from other headers.

The intel cdclk state macros in intel_cdclk.h still reference struct
drm_i915_private, but as macros they don't strictly require the
definition until they are used.

v2: Expand on the commit message wrt cdclk state macros
