Subject: [PATCH v3 0/2] media: imx-jpeg, Add support for contiguous NV12

mxc-jpeg supports non contiguous format nv12m,
and in order to compatible with the devices
who only supports contiguous format nv12,
jpeg can support nv12 and nv12m in the same time.

And client needs to calculate plane size for format NV12.
driver needs to report the aligned resolution,
otherwise they can't the correct uv address.
So driver needs to implement g_selection to report
the actual picture size.

v3
- correct the strm_bufsize of encoder

v2
- correct the target V4L2_SEL_TGT_COMPOSE_PADDED of decoder
- add Fixes tag
