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.

Improve the pxp_soft_reset() error message by moving it to the
caller function, associating it with a proper device and also
by displaying the error code.

pxp_soft_reset() may fail with a timeout, so it is better to propagate
the error in this case.

clk_prepare_enable() may fail, so we should better check its return value
and propagate it in the case of error.

Add a V4L2 mem-to-mem scaler/CSC driver for the Pixel Pipeline (PXP)
version found on i.MX6ULL SoCs. A similar variant is used on i.MX7D.
Since this driver only uses the legacy pipeline, it should be reasonably
easy to extend it to work with the older PXP versions found on i.MX6UL,
i.MX6SX, i.MX6SL, i.MX28, and i.MX23.
The driver supports scaling and colorspace conversion. There is
currently no support for rotation, alpha-blending, and the LUTs.
