Biju Das 0a9d6ef64e irqchip/renesas-rzv2h: Add struct rzv2h_hw_info with t_offs variable
The ICU block on the RZ/G3E SoC is almost identical to the one found on
the RZ/V2H SoC, with the following differences:

 - The TINT register base offset is 0x800 instead of zero.
 - The number of GPIO interrupts for TINT selection is 141 instead of 86.
 - The pin index and TINT selection index are not in the 1:1 map
 - The number of TSSR registers is 16 instead of 8
 - Each TSSR register can program 2 TINTs instead of 4 TINTs

Introduce struct rzv2h_hw_info to describe the SoC properties and refactor
the code by moving rzv2h_icu_init() into rzv2h_icu_init_common() and pass
the variable containing hw difference to support both these SoCs.

As a first step add t_offs to the new struct and replace the hardcoded
constants in the code.

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.
