Include object files of gk20a, gm20b and vgpu in the same composite
object nvgpu.o in the top-level makefile, and remove the old makefiles.
This helps in building the driver as a separate module.

The nvgpu driver now supports using the Tegra graphics virtualization
interfaces to support gk20a in a virtualized environment.

This patch adds support for executing a precompiled GPU program to
allow exporting GPU buffers to other graphics units that have color
decompression engine (CDE) support.

When moving compression state tracking and compbit management ops to
kernel, we need to attach a fence to dma-buf metadata, along with the
compbit state.
To make in-kernel fence management easier, introduce a new gk20a_fence
abstraction. A gk20a_fence may be backed by a semaphore or a syncpoint
(id, value) pair. If the kernel is configured with CONFIG_SYNC, it will
also contain a sync_fence. The gk20a_fence can easily be converted back
to a syncpoint (id, value) parir or sync FD when we need to return it to
user space.
Change gk20a_submit_channel_gpfifo to return a gk20a_fence instead of
nvhost_fence. This is to facilitate work submission initiated from
kernel.

Add semaphore_gk20a.c/h that implement a new semaphore management API
for the gk20a driver. The API introduces two entities, 'semaphore pools'
and 'semaphores'.
Semaphore pools are memory areas dedicated for hosting one or more
semaphores. Typically, one pool equals one 4K page. A semaphore pool
is always mapped to the kernel memory, and it can be mapped and
unmapped to gpu address spaces using gk20a_semaphore_pool_map/unmap.
Semaphores are backed by 16 bytes of memory allocated from a semaphore
pool. The value of a semaphore can be 0=acuired or 1=released. When
allocated, the semaphores are initialized to the acquired state. They
can be released, or their releasing can be waited for by the CPU or GPU.
Semaphores are intended to be used only once, and after they are
released they should be freed so that the slot within the semaphore
pool can be reused. However GPU jobs must take references to the
semaphores that they use (similarly as they take references on memory
buffers that they use) so that the semaphore backing memory is not
reused too soon.
