drm/i915/gem: Break out some shmem backend utils
Break out some shmem backend utils for future reuse by the TTM backend:
shmem_alloc_st(), shmem_free_st() and __shmem_writeback() which we can
use to provide a shmem-backed TTM page pool for cached-only TTM
buffer objects.
Main functional change here is that we now compute the page sizes using
the dma segments rather than using the physical page address segments.
v2(Reported-by: kernel test robot <lkp@intel.com>)
- Make sure we initialise the mapping on the error path in
shmem_get_pages()
