drm/ttm: rework on ttm_resource to use size_t type

Browse Source 
Change ttm_resource structure from num_pages to size_t size in bytes.
v1 -> v2: change PFN_UP(dst_mem->size) to ttm->num_pages
v1 -> v2: change bo->resource->size to bo->base.size at some places
v1 -> v2: remove the local variable
v1 -> v2: cleanup cmp_size_smaller_first()
v2 -> v3: adding missing PFN_UP in ttm_bo_vm_fault_reserved
