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.
