This patch fixes incorrect interrupt induced by m2m operation.
the m2m operation calls s/w reset every frame but there is the case that
the interrupt to m2m operation occures after s/w reset sometimes.
So this patch makes dma and capture operations stop at s/w reset
to avoid incorrect interrupt.

This patch fixes erroneous register read.
reall function needs register base address + offset but

This patch fixes the issue that when buffer allocation is requested
without iommu, the allocation is failed.

Without iommu, dma_alloc_attrs function allocates some memory region
and returns cpu address so this patch makes the cpu address to be set
to buf->kvaddr correctly.

Changelog v2:
- fix buffer free
  . Without iommu, dma_free_attrs function requires kernel space address
    as argument. So it changes the argument, buf->pages to buf->kvaddr.

This patch considers no iommu support to kernel space mapping
of console framebuffer.

Without iommu, we get physical address instead of device address

kernel space.

  Based on Chris' fix for SNA, now also for UXA/mesa&old SNA.
- Some more fixlets for shrinker-pulls-the-rug issues (Chris&me).
- Fix dma-buf flags when exporting (you).
- Disable the VGA plane if it's enabled on lid open - similar fix in
