drm/i915/wm: move remaining watermark code out of intel_pm.c Add new files intel_wm.[ch] and i9xx_wm.[ch] under display/ to hold generic and pre-SKL watermark code, respectively. SKL+ watermark code has already been split out to skl_watermark.[ch]. Use the _wm.[ch] naming for brevity; we may want to rename skl_watermark.[ch] later accordingly. Add new intel_wm_init() to call either skl_wm_init() or i9xx_wm_init(i915) depending on the platform, the latter comprising of the remains of intel_init_pm(). Sprinkle in some minor checkpatch fixes while moving the code. v2: - Rebase - Fix copyright year Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/ddf04a07a37f0368b3fef85d4ebb924082fec6cd.1676317696.git.jani.nikula@intel.com
