From: Michal Srb <msrb@xxxxxxxx>
The io_mem_pfn field was added in ea642c3216cb2a60d1c0e760ae47ee85c9c16447 and
is used unconditionally. Most drivers were updated to set it to the default
implementation ttm_bo_default_io_mem_pfn, but hibmc was not.
This fixes crash in ttm_bo_vm_fault when hibmc driver is used.
