sunxi: SPL SPI: Add SPI boot support for the Allwinner R40 SoC
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.
