sunxi: SPL SPI: add support for the V3s SoC

Browse Source 
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.

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
