Add support for the Renesas RZ/T2H (R9A09G077) SoC, which features a different interrupt layout for the RIIC controller. Unlike other SoCs with individual error interrupts, RZ/T2H uses a combined error interrupt (EEI). Introduce a new IRQ descriptor table for RZ/T2H, along with a custom ISR (`riic_eei_isr`) to handle STOP and NACK detection from the shared interrupt.

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.
