The era of hand-rolled HIWORD_UPDATE macros is over, at least for those drivers that use constant masks. Remove this driver's very own HIWORD_UPDATE macro, and replace all instances of it with equivalent instantiations of FIELD_PREP_WM16 or FIELD_PREP_WM16_CONST, depending on whether it's in an initializer. This gives us better error checking, and a centrally agreed upon signature for this macro, to ease in code comprehension. Because FIELD_PREP_WM16/FIELD_PREP_WM16_CONST shifts the value to the mask (like FIELD_PREP et al do), a lot of macro instantiations get easier to read. This was tested on an RK3568 ODROID M1, as well as an RK3399 ROCKPro64.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
