Implement NVGPU_AS_IOCTL_GET_VA_REGIONS which returns a list of GPU VA
regions for different page sizes. This is required for the userspace
for safe fixed-address address space allocation.

Add the following info into GPU characteristics: available big page
sizes, support indicators for sync fence fds and cycle stats, gpc
mask, SM version, SM SPA version and warp count, and IOCTL interface
levels. Also, add new IOCTL to fetch TPC masks.

Some kernel APIs rely on user space knowing class numbers. Allow
querying the numbers from kernel.

Kernel support for allowing a GPU debugger to suspend and resume
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.

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.

Correct some old comments and remove uses of the BIT macro to make it
easier to sync this file to userspace.

Move nvgpu ioctls from the many user space interface headers to a new
single nvgpu.h header under include/uapi. No new code or replaced names
are introduced; this change only moves the definitions and changes
include directives accordingly.

Tegra graphics virtualization (host1x syncpoint and gpu) is now
exposed to client drivers (nvhost and nvgpu). These interfaces
rely on a communication framework to communicate with the server
driver that actually implements the back-end routines.

Move all channel synchronization code to new channel_sync_gk20a.c/h
files, and access all synchronization functions through function
pointers. This is groundwork for supporting semaphore based channel
synchronization.
