[PATCH v4 2/4] drm/ttm: Clean up page shift operation

[Somalapuram Amaranath <Amaranath.Somalapuram@amd.com>]

Remove page shift operations as ttm_resource moved
from num_pages to size_t size in bytes.
v1 -> v2: fix missing page shift to fpfn and lpfn
v2 -> v3: separate patches based on driver module
