[PATCH 3/7] drm/amdgpu: Add per-ASIC PTE init flag

[Alex Deucher <alexander.deucher@amd.com>]

From: Mukul Joshi <mukul.joshi@amd.com>

On GFX12.1, default PTE setup needs an additional bit to be
set. Add PTE initialization flags to handle setup default PTE
on a per-ASIC basis.
While at it, fixup the coding style too.
