If a stream is stopped, or if a USERPTR/DMABUF buffer is queued
backed by a different user address or dmabuf fd, then the timestamp
should be skipped by vb2_find_timestamp since the memory it refers
to is no longer valid.
So keep track of a 'copied_timestamp' state: it is set when the
timestamp is copied from an output to a capture buffer, and is
cleared when it is no longer valid.

Buffers generated with YUV32 format seems to be incorrect, hence use
VUYA32 instead.
Changes from v1:
Add both formats VUYA32 and VUYX32 but associate only VUYX32 to the
output queue as the alpha channel of buffers is ignored on this queue.

V4L2_PIX_FMT_XYUV32
V4L2_PIX_FMT_VUYA32
V4L2_PIX_FMT_VUYX32
These formats enable the trasmission of alpha channel data to other
drivers and userspace applications in addition to YUV data. For
example, buffers generated by drivers in one of these formats
can be used by the Weston compositor to display as a texture or
flipped directly onto the overlay planes with the help of a DRM
