[0/3] Add Himax hx83112b touchscreen driver

This series adds support for the Himax hx83112b. The hx83112b supports 10
point multitouch with hardware tracking of touch points. It is the
touchschreen used by the Fairphone 3.

Note that a datasheet was unavailable for this device, so it was built
based on the Android driver that was tagged as GPLv2. This series is a
complete rewrite, though, and the code bears no resemblence to the original
implementation.

It is expected that this driver can be made to work on other hx83xxx
devices, especially the hx83112a used in the Fairphone 4. However, since we
have been unable to verify this, this driver only declares compatibility
with the hx83112b and uses very specific file names.

This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit.
