[PATCH -next] drm/i915/wm: Fix some kernel-doc comments

[Yang Li]

Make the description of @dev_priv to @i915 to silence the warnings:
drivers/gpu/drm/i915/display/intel_wm.c:46: warning: Function parameter or member 'i915' not described in 'intel_update_watermarks'
drivers/gpu/drm/i915/display/intel_wm.c:46: warning: Excess function parameter 'dev_priv' description in 'intel_update_watermarks'
