3fdb6d2e31 gpu: nvgpu: Remove Linux headers from mm_gk20a.h
Delte the Linux headers and make some modifications to get rid of the
minor compilation issues that resulted.

  - Add <linux/iommu.h> to os_linux.h
  - Delete #if 0 code that "flushed" a buffer in gr_gk20a.c
  - Delete FLUSH_CPU_DCACHE() macro
  - Move the cache flush definitions to <nvgpu/linux/vm.h>
    and include this header in sim_gk20a.c. This file will
    not be used by QNX so this should be fine.
  - Add <linux/pci_ids.h> to gp106/bios_gp106.c and
    gp106/mclk_gp106.c.
  - Move function to common/linux/dmabuf.h since it is a
    dmabuf related function and uses a struct device pointer
    as an argument.

b3446bc0b6 gpu: nvgpu: Move dma_buf usage from mm_gk20a.c
Move most of the dma_buf usage present in the mm_gk20a.c code
out to Linux specific code and some commom/mm code. There's
two primary groups of code:

  1. dma_buf priv field code (for holding comptag data)
  2. Comptag usage that relies on dma_buf pointers

For (1) the dma_buf code was simply moved to common/linux/dmabuf.c
since most of this code is clearly Linux specific.

The comptag code was a bit more complicated since there is two
parts to the comptag code. Firstly there's the code that manages
the comptag memory. This is essentially a simple allocator. This
was moved to common/mm/comptags.c since it can be shared across
all chips. The second set of code is moved to
common/linux/comptags.c since it is the interface between dma_bufs
and the comptag memory.

Two other fixes were done as well:

 - Add struct gk20a to the comptag allocator init so that
   the proper nvgpu_vzalloc() function could be used.
 - Add necessary includes to common/linux/vm_priv.h.
