The following patch fixes the SPI not working with H6 SoCs. I encountered this on a pine H64 model B board when trying to configure u-boot to work with the on-board SPI flash. Register inspection showed that the pins were configured for the wrong function '0b011' which is the SD/eMMC interface instead of '0b100' which is needed for SPI. See Allwinner H6 datasheet section '3.21.5.1 PC Configuration Register 0'.
I also saw that a new config symbol CONFIG_SUN50I_GEN_H6 was introduced and the SPI driver could probably be converted to that one to also work for H616 SoCs. Since I don't have any Allwinner H616 based board available for testing I didn't approach this.
The SPL SPI driver is not effected by this, since the correct conditional logic was already implemented there.
