[SRU] [OEM-5.10] [PATCH 0/3] Fix i915 warnings on skl_dram_get_channel_info()

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1943923

[Impact]
Kernel warning from i915's skl_dram_get_channel_info().

[Fix]
Update how i915 gets DRAM information.

[Test]
No more kernel splat after the fix gets applied.
Anything graphics related seems to work fine.

[Where problems could occur]
The change only applies to gen11 and gen12 gfx so the scope is limited.
If the PCODE doesn't work as intended, this might cause regression.

José Roberto de Souza (3):
  drm/i915: Nuke not needed members of dram_info
  drm/i915/gen11+: Only load DRAM information from pcode
  drm/i915: Rename is_16gb_dimm to wm_lv_0_adjust_needed
