Use busy looping for l2 tag flush and elpg flush
operations. This is making total flash time more
accurate and reduced overall time compared with
usleep. Also added trace points to measure
performance for these operations.
Also corrected timeout error check for non-silicon
platforms.

CUDA devtools need to be able to flush the GPU's cache
in a sideband fashion and so cannot use methods. This
change implements an nvgpu_gpu_ioctl to flush and
optionally invalidate the GPU's L2 cache and flush fb.

Add the ioctl to open a new gpu channel to also the control node for
improved process startup performance, in addition to the current open
ioctl in the channel node. The new channel fd creation is refactored to
a separate function which is called from both ctrl and channel ioctls.

Add a couple of trace points for tracking when we need to wait for
space in the gpfifo ring buffer. This wait can introduce significant
latencies to rendering with large gpfifo entry inputs so it's good to
be able to measure how often this path is taken.

Implement support for 64kB large page size. Add an API to create an
address space via IOCTL so that we can accept flags, and assign one
flag for enabling 64kB large page size.
Also adds APIs to set per-context large page size. This is possible
only on Maxwell, so return error if caller tries to set large page
size on Kepler.
Default large page size is still 128kB.
