[Intel-gfx] [PATCH 01/12] drm/i915/de: Add more macros to remove all direct calls to uncore

[Jani Nikula]

From: Maarten Lankhorst <maarten.lankhorst at linux.intel.com>

Add more de helpers to be able to avoid direct calls to uncore.

v2 by Jani:
- drop pcode stuff for now
- rename intel_de_write_samevalue -> intel_de_rewrite_fw
