Of all the defconfigs that have ARCH_ROCKCHIP, only three don't have MMC_DW:

    configs/coolpi-cm5-genbook-rk3588_defconfig
    configs/evb-rv1108_defconfig
    configs/geekbox_defconfig

So maybe we could have the default by y, and negate the option where
it makes sense.

For MMC_SDHCI there would be more defconfigs, but only a couple SoCs
support this controller, and we could narrow it down to those.
