Use newly added R-Car GPIO Gen1 fallback compat string
in place of now deprecated non-generation specific
R-Car GPIO fallback compat string in DT of r8a7778 SoC.
As the driver does not match on "renesas,gpio-r8a7778" there
are some run-time considerations for this patch:
* When a resulting DTB is used with kernels newer than v4.14 this should
not have any run-time effect as renesas,rcar-gen1-gpio is matched by the
driver since commit dbd1dad2ab ("gpio: rcar: add gen[123] fallback
compatibility strings")
* However, when used with older kernels GPIO will be disabled as
no compat string match will be made by the driver.
The regression documented above for the new DTB with old kernel case
is acceptable in my opinion.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
