Writing to eMMC using HS200 mode work more reliably then other modes on RK356x boards. Add device tree props and enable Kconfig options for eMMC HS200 mode on the generic RK3566/RK3568 board. Also enable the pinctrl driver in SPL and add missing rk3568-generic.dtb to Makefile. Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
