gpu: nvgpu: gm20b: WPR size 0, on railgate exit
Bug 200066741
ACR ucode has mechanism to skip WPR blob copy for second time,
in case WPR size is sent as 0 to acr ucode.
With above there is a saving of around 0.5 ms, but, in
conjunction with acr change to disable LS sig verification,
and scrubbing empty spaces in WPR sections to 0. This change
can reduce railgate exit latency by 4ms
ACR ucodes to be checked in main, as a different CL, and after
getting prod signs for ACR
