drivers/gpu/drm/gma500/: change return type to vm_fault_t
Use new return type vm_fault_t for fault handler. For now, this is just
documenting that the function returns a VM_FAULT value rather than an
errno. Once all instances are converted, vm_fault_t will become a
distinct type.
Ref-> 1c8f422059ae ("mm: change return type to vm_fault_t")
Previously vm_insert_{pfn,mixed} returns err which driver mapped into
VM_FAULT_* type. The new function vmf_insert_{pfn,mixed} will replace
this inefficiency by returning VM_FAULT_* type.
vmf_error() is the newly introduce inline function in 4.17-rc6.
