drm/amd/display: fix the white screen issue when >= 64GB DRAM
Dropping bit 31:4 of page table base is wrong, it makes page table
base points to wrong address if phys addr is beyond 64GB; dropping
page_table_start/end bit 31:4 is unnecessary since dcn20_vmid_setup
will do that. Also, while we are at it, cleanup the assignments using
upper_32_bits()/lower_32_bits() and AMDGPU_GPU_PAGE_SHIFT.
