In preparation to add support for new SoCs having a different register layout, add an enumeration that documents register offsets and move the definitions for the same to a u32 array; Selecting the right register offsets array is done by adding an of_device_id array containing all of the currently supported compatible strings pointing to the "v1" offsets array (as data): since no devicetree declares the `mediatek,mtk-cirq` compatible without a SoC-specific one, it wasn't necessary to provide any legacy fallback. Every usage of the aforemementioned definitions was changed to get a register address through a newly introduced `mtk_cirq_reg()` accessor. This change brings no functional changes.

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 Restructured Text 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.
