drm/amdgpu: fix 4-level paging if GMC supports 57-bit VA v2
It turned that using 4 level page tables on GMC generations which support
57bit VAs actually doesn't work at all.
Background is that the GMC actually can't switch between 4 and 5 levels,
but rather just uses a subset of address space when less than 5 levels are
selected.
Philip already removed the automatically switch to 4levels, now fix it as
well should it be enabled by module parameters.
v2: fix AMDGPU_GMC_HOLE_MASK as well, fix off by one issue pointed out
