Let mmap method to use dma_mmap_coherent call. Moreover, this patch removes
vb2_mmap_pfn_range from videobuf2 helpers as it was suggested by Laurent
Pinchart. The function is no longer used in vb2 code.

This patch adds extension to V4L2 api. It allow to export a mmap buffer as file
descriptor. New ioctl VIDIOC_EXPBUF is added. It takes a buffer offset used by
mmap and return a file descriptor on success.

This patch adds taking reference to the device for MMAP buffers.
Such buffers, may be exported using DMABUF mechanism. If the driver that
created a queue is unloaded then the queue is released, the device might be
released too. However, buffers cannot be released if they are referenced by
DMABUF
From: Marek Szyprowski
The DMA transfer must be aligned to a specific value. If userptr is not aligned
to DMA requirements then unexpected corruptions of the memory may occur before
or after a buffer. To prevent such situations, all unligned userptr buffers
are rejected at VIDIOC_QBUF.

--- Comment #21 from Alex Deucher ---
I've gone ahead and re-pushed v2 of the patch. The lower voltages are are to
support the higher mclks, so there's no need to keep them high. They only need
to be adjusted up when both clocks are raised.
