Debarshi Dutta ac2dfc554f gpu: nvgpu: address VPR resize for deterministic channels 
UMD is unable to restrict railgate for deterministic channels
when NVGPU_CAN_RAILGATE is set to false. This causes issues
with VPR resize as there is no means of preventing an active
VPR resize in progress.

Add a fault handler for usermode region. The fault handler's purpose is
to intercept UMD accesses into the doorbell region when a GPU reset
is in progress. GPU reset could be triggered by VPR resize. During a
reset, the corresponding PTEs for the usermode region are zapped. The
fault handler tries to have a read access to g->deterministic_busy
and blocks till the reset is finished. A VPR resize is guaranteed
to be mutually exclusive due to use of the g->deterministic_busy
RW semaphore.
