895675e1d5 gpu: nvgpu: Removal of regops from CUDA driver
The current CUDA drivers have been using the regops to
directly accessing the GPU registers from user space through
the dbg node. This is a security hole and needs to be avoided.
The patch alternatively implements the similar functionality
in the kernel and provide an ioctl for it.

364156cdcd gpu: nvgpu: Pre-Population of zbc entries
The default zbc entries were never populated in zbc HW table
because the conditional flag "gr->sw_ready" was always set thus
avoided the zbc default loading function call. Now zbc default
loading would happen only during boot time in sw structure.Hw
zbc regs would be loaded from that structure every time a
railgate exit happens.

SMs. Invocation of "suspend" on a given channel will suspend all
SMs if the channel is resident, else remove the channel form the
runlist. Similarly, "resume" will either resume all SMs if the
channel was resident, or re-enable the channel in the runlist.
