This is a very old driver for very old hardware and it is one of
the very few remaining that does not use the vb2 framework (or
even the older videobuf framework), so deprecate this driver
and move it to staging with the intent to removing it altogether
by the end of 2022.
If someone wants to keep this driver, then it has to be converted
to use vb2.

This inserts 4 pixels of the RGB color 0xab55ab at the left hand side of
the image. This is only done for 3 or 4 byte RGB pixel formats. The HDMI
TMDS encoding of this pixel value equals the Video Guard Band value as
defined by HDMI (see section 5.2.2.1 in the HDMI 1.3 Specification) that
preceeds the first actual pixel of a video line. If an HDMI receiver
doesn't handle this correctly, then it might keep skipping these Video
Guard Band patterns and end up with a shorter video line. So this is a
nice pattern to test with.

To simplify the driver's maintenance it makes sense to escape from
hardcoded numbers of power domain resources per platform and statical
allocation of the resources. For instance on a QCOM SM8450 platform
the number of CAMSS power domains shall be bumped up to 6, also notably
CAMSS on MSM8916 has only one power domain, however it expects to get 2,
and thus it should result in a runtime error on driver probe.
The change fixes an issue mentioned above and gives more flexibility
to support more platforms in future.

This replaces all of the dprintk macro calls with the zrdev_dbg,
zrdev_info, or zrdev_err calls as appropriate. This allows for the
removal of the dprintk macro from each file it is defined in, along with
the removal of module params that track the debugging level.
In the case that the debugging level was used in a comparison, this has
been replaced with checking the console level debugging and making a
decision from there. If the console debugging level is at least the
KERN_ debugging level equivalent, then the comparison will evaluate as
true.
There are a few instances where pr_debug must be used over the
zrdev_dbg. These occur in the module cleanup functions because there
should be no devices defined once we get here, so we don't have a device
to pass to zrdev_dbg.
