[PATCH] sunxi: SPL SPI: add support for the V3s SoC

[Michael Walle]

The V3s is identical regarding register layout, clocks and resets to
the sun6i variants. Therefore, we can just add the MACH_SUN8I_V3S to
the sun6i compatible ones.

SPI boot was tested on a custom board with a Gigadevice GD25Q64 8MiB
SPI flash.
