d148738923 drm/i915/ttm Initialize the ttm device and memory managers 
Temporarily remove the buddy allocator and related selftests
and hook up the TTM range manager for i915 regions.

Also modify the mock region selftests somewhat to account for a
fragmenting manager.

c538d54e49 drm/i915: Distinction of memory regions 
In preparation for Xe HP multi-tile architecture with multiple memory
regions, we need to be able differentiate multiple instances of device
local-memory.

Note that the region name is just to give it a human friendly
identifier, instead of using class/instance which also uniquely
identifies the region. So far the region name is only for our own
internal debugging in the kernel(like in the selftests), or debugfs
which prints the list of regions, including the regions name.

v2: add commentary for our current region name use

7c5cc94133 drm/i915/dg1: Reserve first 1MB of local memory 
On DG1 A0/B0 steppings the first 1MB of local memory must be reserved.
One reason for this is that the 0xA0000-0xB0000 range is not accessible
by the display, probably since this region is redirected to another
memory location for legacy VGA compatibility.

BSpec: 50586
Testcase: igt/kms_big_fb/linear-64bpp-rotate-0

v2:
- Reserve the memory on B0 as well.

v3: replace DRM_DEBUG/DRM_ERROR with drm_dbg/drm_err

a50ca39fbd 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.

- 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
