soc: rockchip: grf: Fix SDMMC not working on RK3588 with bus-width > 1 



RK3588 has the same issue as other earlier RK SoCs. JTAG
functionality muxed to some SDMMC data pins causes issues with SDMMC
interface. Without this patch, I can only use SDMMC inteface
with bus-width = <1>. (JTAG is muxed to data pins D2 and D3)
