Add the driver for the HiSilicon v3xx SPI NOR flash controller, commonly found in hi16xx chipsets. This is a different controller than that in drivers/mtd/spi-nor/hisi-sfc.c; indeed, the naming for that driver is poor, since it is really known as FMC, and can support other memory technologies. The driver module name is "hisi-sfc-v3xx", as recommended by HW designer, being an attempt to provide a distinct name - v3xx being the unique controller versioning. Only ACPI firmware is supported. DMA is not supported, and we just use polling mode for operation completion notification. The driver uses the SPI MEM OPs.

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.
