Add i.MX8MQ support and Fix read.
When offset is not 4 bytes aligned, directly shift righty by 2 bits
will cause reading out wrong data. Since imx ocotp only supports
4 bytes reading once, we need handle offset is not 4 bytes aligned
and enlarge the bytes to 4 bytes aligned. After finished reading,
copy the needed data from buffer to caller and free buffer.

MLK-16205 video: fbdev: dcss: handle cfifo wrapping case
As time goes on, the cfifo buffer is close to be
exausted. And since the cfifo is a ring buffer,
so at this moment, the cfifo needs to be wrapped
to the buffer beginning. In this driver, the fifo
wrapping condition is that the free size to buffer
end is less than the commit size. And before the
buffer wrapping, the 'ctxld_wq' workqueue needs to
be flushed to make sure all the previous commited
jobs to be finished. Besides, this commit ...

This patch adds LVDS to HDMI it6263 bridge(s) support on the i.MX8qxp MEK
platform. Since the platform supports up to two it6263 bridge(s) via
daughter cards plugged into mini-SAS connectors, this patch introduces
several DT sources so that users may choose relevant DT blob to use
