Add the DRIF controller nodes for the r8a77990 (a.k.a. R-Car E3). Please note that R-Car E3 has register BITCTR located at offset 0x80 (this register is not available on the r8a77960 and r8a77951, whose support has already been upstreamed), and even though it is not dealt with just yet within the driver, we have to keep that into account with our device tree nodes. Also, please note that while testing it has emerged that the HW User Manual has the wrong DMA details for DRIF2 and DRIF3 on E3, as they are only allowed SYS-DMAC0 rather than SYS-DMAC1 and SYS-DMAC2. An errata addressing this issue will be available soon.

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.
