gpu: nvgpu: abstract away ioctl gpfifo read
The biggest remaining Linuxism in the submit path is the
copy_from_user() calls for reading the gpfifo entries to the HW-visible
buffer. Abstract away the copy of one such segment starting at some
offset and keep the wraparound logic and vidmem proxy in the core submit
path.
