gpu: nvgpu: add submit entry points for kernel and ioctl

Browse Source 
gk20a_submit_channel_gpfifo() supports reading the gpfifo entries from
either a kernel buffer or an userspace buffer in an ioctl. Add two
separate entry points: one for the ioctl and another for any other
kernel use. This shortens the function prototypes and simplifies and
clarifies the call sites slightly.
