Fabrizio Castro 9002b75aa8 irqchip/renesas-rzv2h: Add rzv2h_icu_register_dma_req()
On the Renesas RZ/V2H(P) family of SoCs, DMAC IPs are connected
to the Interrupt Control Unit (ICU).
For DMA transfers, a request number must be registered with the
ICU, which means that the DMAC driver has to be able to instruct
the ICU driver with the registration of such id.

Export rzv2h_icu_register_dma_req() so that the DMAC driver can
register the DMAC request number.

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.
