Brightness settings for HIMX11B1 sensor were not correctly set so the
video output stream is almost completely dark.


Two commits from https://github.com/intel/ipu6-drivers are required to
fix this. Actually the second one is to correct the compiling errors
against 5.13 kernel that was introduced accidentally in the first commit.

[Test Case]

Run cheese on supported platform to grap video output stream for check.

[Where problems could occur]

This is the first time we have this sensor up and running with
meaningful output on real hardware. Expecting possible quality
adjustments and so on.

[Other Info]

While Intel doesn't officially commit the plan to upstream IPU6 driver,
we will only carry this on oem kernels. And since IPU6 oem-5.10
platforms are migrating to oem-5.13 as well, and we have neither 5.10
platforms with hm11b1 sensor previously, we're skipping oem-5.10 here.
