The planar YUV422P is quite unusual and few if any applications support it.

All fields after 'type' are already zeroed by the core framework.
Clearing the full struct also clears 'type', which causes a wrong
type value to be returned.

Instead of comparing against STD_NTSC and STD_PAL compare against 60 and
50 Hz formats. That's what you really want.
When the standard is changed, make sure the width and height of the format
are also updated to reflect the current standard.
Also replace the deprecated current_norm by the g_std ioctl.

Instead use v4l2_dbg and v4l2_err. Note that the PDEBUG macro is kept to
make this patch-set less invasive, but it is simply a wrapper around
v4l2_dbg now. Most of the other changes are there to make the dev parameter
for the v4l2_xxx macros available everywhere we do logging.

Ensure the driver gets always at least its minimum required
number of buffers allocated by checking actual number of
allocated buffers in vb2_reqbufs(). And free any partially
allocated buffer queue with signaling an error to user space.
Without this patch applications may wait forever to dequeue
a filled buffer, because the hardware didn't even start after
VIDIOC_STREAMON, VIDIOC_QBUF calls, due to insufficient number
of empty buffers.

Not all drivers use monotonic timestamps. This patch adds a way to set the
timestamp type per every queue.
In addition, set proper timestamp type in drivers that I am sure that use
either MONOTONIC or COPY timestamps. Other drivers will correctly report
UNKNOWN timestamp type instead of assuming that all drivers use monotonic
timestamps.
