1. Before destroying the allocator for PMU dmem check if it was already
initialized. It is only initialized through certain paths like PMU ISRs.
So while testing the nvgpu module using nvgpu_submit_twod test I found
that it was never initialized.
2. Inside gk20a_init_gr_setup_sw, cleanup part calls for de-allocating
the already allocated chunk of memory. Whereas, cleanup also gets called
when memory allocation inside the same function fails. In such cases,
we should have a non-null check else we attempt to free a non-allocated
memory and kernel panics.

Implement a new buddy allocation scheme for the GPU's VA space.
The bitmap allocator was using too much memory and is not a scaleable
solution as the GPU's address space keeps getting bigger. The buddy
allocation scheme is much more memory efficient when the majority
of the address space is not allocated.
The buddy allocator is not constrained by the notion of a split
address space. The bitmap allocator could only manage either small
pages or large pages but not both at the same time. Thus the bottom
of the address space was for small pages, the top for large pages.
Although, that split is not removed quite yet, the new allocator
enables that to happen.
The buddy allocator is also very scalable. It manages the relatively
small comptag space to the enormous GPU VA space and everything in
between. This is important since the GPU has lots of different sized
spaces that need managing.
Currently there are certain limitations. For one the allocator does
not handle the fixed allocations from CUDA very well. It can do so
but with certain caveats. The PTE page size is always set to small.
This means the BA may place other small page allocations in the
buddies around the fixed allocation. It does this to avoid having
large and small page allocations in the same PDE.

-Moved bind fecs from work queue to init_gr_support.
-It makes all CPU->FECS communication to happen before
booting PMU, and after we boot PMU, only PMU talks to
FECS. So it removes possibility to race between CPU
and PMU talking to FECS.

GK20A PMU is not supported in GPU client for virtualization. However,
to make native case and virtualization case can share same defconfig and
kernel image, we need to enable CONFIG_GK20A_PMU and
CONFIG_GK20A_DEVFREQ in defconfig. This commit changes to detect if we
should disable GK20A PMU support in run time.

The return value of gk20a_busy must be checked since it may not succeed
in some cases. Add the __must_check attribute that generates a compiler
warning for code that does not read the return value and fix all uses of
the function to take error cases into account.

To help remove the nvhost dependency from nvgpu, rename ioctl defines
and structures used by nvgpu such that nvhost is replaced by nvgpu.
Duplicate some structures as needed.
