BootROM leave GPIO4_D6 configured as SDMMC_PWREN function and DW MMC

However, HW revision prior to v1.2 must pull GPIO4_D6 low to access
sdmmc. For HW revision v1.2 the state of GPIO4_D6 has no impact.
Upstream linux-rockchip maintainer tree has merged a patch "arm64: dts:
rockchip: Fix sdmmc access on rk3308-rock-s0 v1.1 boards" for v6.14 to
fix this issue.
Would have been nice to provide the commit hash here so we can check
against it ourselves :)

Looks good otherwise,
