Now that we can easily select an SoC specific SPI0 base address, adding
support for the Allwinner R40 is fairly trivial:
We set the base address, add this SoC to the ones that use PC23 and
enable it in Kconfig.
This allows booting from SPI flash on R40 boards.
Tested on a Bananapi M2 Berry with SPI flash connected to the header pins.

Enable support for SPI Flash. This option allows SPL to read from
sunxi SPI Flash. It uses the same method as the boot ROM, so does
