MLK-20753: mxc-jpeg: Switch from single to multi-planar v4l2 buffers

Adjust the driver to use the "mplane" flavor of v4l2 structures:
"mplane" flavor ioctls for format negotiation in mxc_jpeg_ioctl_ops,
V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE instead of V4L2_BUF_TYPE_VIDEO_CAPTURE,
V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE instead of V4L2_BUF_TYPE_VIDEO_OUTPUT,
V4L2_CAP_VIDEO_M2M_MPLANE instead of V4L2_CAP_VIDEO_M2M,
pix_mp member of struct v4l2_format, instead of pix (previously, the
pix_mp was sometimes used wrongly for single-plane).

Adjust the sizeimage & bytesperline members of mxc_jpeg_q_data
as MXC_JPEG_MAX_PLANES elements arrays, to accommodate maximum 2 planes.

In case of YUV420, which is the only multi-planar format supported,
use the first plane address as buf_base0 and the second plane address
as buf_base1, to configure the CAST IP. Previously, the buf_base1 was
calculated as an offset to buf_base0, in mxc_jpeg_addrs.

After decoding, set the payload for both planes via vb2_set_plane_payload.

Multi-planar support current status:
-gst-launch with filesink & fbdevsink always pass
-gst-launch with waylandsink & kmssink sometimes fail for resolutions
where height is multiple of 256 (1024 x 256, 1024 x 512).
