Fix the videobuf2-rdma-sg to videobuf2-cma-sg, and move it into
videobuf2 directory.
The videobuf2-cma-sg almost keep same as videobuf2-rdma-sg, both of them
are referenced from videobuf2-dma-sg. But the videobuf2-cma-sg also
support the videobuf2-dma-sg if the device's attr without force
contiguous attr.

The hdmirx allocates memory through videobuf2 and call the
vb2_dma_contig_ops, but the hdmirx not select the VIDEOBUF2_DMA_CONTIG
itself, but the ISP will select it instead.
When a patch for ISP may not select VIDEOBUF2_DMA_CONTIG, the hdmirx
will fail to compile since not defined videobuf2_dma_contig_ops.
So select VIDEOBUF2_DMA_CONTIG by hdmirx indeed.

Currently videobuf2 supports videobuf2-dma-sg, videobuf2-dma-contig and
videobuf2-vmalloc.
- vb2_dma_sg_memops
created by videobuf2-dma-sg driver,
allocates memory through 'alloc_pages' and manager them with scatter
gather list (sgt).
- vb2_dma_contig_memops
created by videobuf2-dma-contig driver,
allocates memory through dma_alloc_attrs, may result in many kinds of
memory, including 'cma_alloc'.
- vb2_vmalloc_memops
created by videobuf2-vmalloc driver,
allocates memory through vmalloc_user.
In some case device requires allocate memory through cma_alloc and manager
them by sgt, the new driver is named videobuf2-cma-sg.
- vb2_cma_sg_memops
created by videobuf2-cma-sg driver,
allocates memory through 'cma_alloc' and manager them with sgt.

1.Hdmirx DMA caused NOC abnormal pending during hot-plug operation,
resulting in system crash.Detect signal change as soon as possible
and reset hdmirx controller in FIQ to avoid hdmirx DMA exception.
2.Add hdmirx DMA reset operation when HDMI is unplugged and hdmirx
DMA is off.

1. Get timing from hdmirx ctrl.
2. If the timing is error, get timing from dma.
3. If get timing error from dma, re-execute hotplug process.
