H A Dintel_region_lmem.ha50ca39f Wed Jan 27 07:14:11 CST 2021 Matthew Auld <matthew.auld@intel.com> drm/i915: setup the LMEM region

Hook up the LMEM region. Addresses will start from zero, and for CPU
access we get LMEM_BAR which is just a 1:1 mapping of said region.

Based on a patch from Michel Thierry.

v2 by Jani:
- use intel_uncore_read/intel_uncore_write
- remove trailing blank line

v3: s/drm_info/drm_dbg for info which in non-pertinent for the user
