Add pins, groups, and functions for the SPI Multi I/O Bus Controller (RPC-IF) to the R8A77990 PFC driver. They are to be used when an Octal-SPI Flash or HyperFlash is connected. Redefine the QSPI[01] pin groups using the RPC DQ[0:7] pin data, to save memory.

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.
