rockchip: mmc: rockchip_dw_mmc: add rk3066/rk3188 support
The Rockchip SoCs rk3066/rk3188 have MMC DT nodes with as compatible string "rockchip,rk2928-dw-mshc". Add OF_PLATDATA support to the existing driver with help of a DM_DRIVER_ALIAS. This type needs a permanent enabled fifo. The other Rockchip SoCs always have the property "u-boot,spl-fifo-mode" in the MMC DT nodes, because MMC to SRAM can't do DMA. Make this property a requirement for MMC OF_PLATDATA structures. The property "fifo-mode" must be added for all other compile modes.
