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.

Changed V5: reword remove driver_data add OF_PLATDATA u_boot_spl_fifo_mode requirement
