[PATCH 3/5] sunxi: spl: spi: Add support for Allwinner A523

[Andre Przywara <andre.przywara@arm.com>]

The SPI IP in the Allwinner A523 is mostly compatible to the later
generation used in other Allwinner SoCs, at least as far as the SPL
driver is concerned.

Just add the pinmux configuration for SPI0 on PortC, as used by the
BROM. This enables SPI (NOR) boot on A523/A527/T527 boards.
