[media] vb2: use dma_map_sg_attrs to prevent unnecessary sync
By default dma_map_sg syncs the mapped buffer to the device. But
buf_prepare expects a buffer syncs for the cpu and the buffer
will be synced to the device in the prepare memop.
The reverse is true for dma_unmap_sg, buf_finish and the finish
memop.
To prevent unnecessary syncs we ask dma_(un)map_sg to skip the
sync.

[media] vb2-dma-sg: move dma_(un)map_sg here
This moves dma_(un)map_sg to the get_userptr/put_userptr and alloc/put
memops of videobuf2-dma-sg.c and adds dma_sync_sg_for_device/cpu to the
prepare/finish memops.
Now that vb2-dma-sg will sync the buffers for you in the prepare/finish
memops we can drop that from the drivers that use dma-sg.
For the solo6x10 driver that was a bit more involved because it needs to
copy JPEG or MPEG headers to the buffer before returning it to userspace,
and that cannot be done in the old place since the buffer there is still
setup for DMA access, not for CPU access. However, the buf_finish
op is the ideal place to do this. By the time buf_finish is called
the buffer is available for CPU access, so copying to the buffer is fine.

The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete(). usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs. The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.

Most are caused by pointers marked as __iomem when they aren't or not marked as
__iomem when they should.
Also note that readl/writel already do endian conversion, so there is no need to
do it again.
saa7164_bus_set/get were a bit tricky: you have to make sure the msg endian
conversion is done at the right time, and that the code isn't using fields that
are still little endian instead of cpu-endianness.
The approach chosen is to convert just before writing to the ring buffer
and to convert it back right after reading from the ring buffer.

[media] adv7604: Correct G/S_EDID behaviour
In order to have v4l2-compliance tool pass the G/S_EDID some modifications
where needed in the driver.
In particular, the edid.reserved zone must be blanked.
Based on a patch from Jean-Michel Hautbois <jean-michel.hautbois@vodalys.com>,
but reworked it a bit. It should use 'data' (which depends on edid.present)
instead of edid.blocks as the check whether edid data is present.

[media] media: davinci: vpbe: missing clk_put
we are getting struct clk using clk_get before calling
clk_prepare_enable. but if clk_prepare_enable fails, then we are
jumping to fail_mutex_unlock where we are just unlocking the mutex,
but we are not freeing the clock source.
this patch just adds a call to clk_put before jumping to
fail_mutex_unlock.

[media] vivid: add test array controls
Add array controls to test support for such controls. There is one
array with just one element, one 8x16 matrix control and one 4 dimensional
2x3x4x5 control.
This makes it possible to experiment with such controls without requiring
hard-to-get hardware.

[media] solo6x10: don't turn off/on encoder interrupt in processing loop
It makes no sense to block the SOLO_IRQ_ENCODER interrupt from being sent while
processing an earlier interrupt. New interrupts will just kick the thread
again once it is done processing.
