rockchip: rk3308-rock-s0: Fix SD-card boot on v1.1 hw revision
BootROM leave GPIO4_D6 configured as SDMMC_PWREN function and DW MMC
driver set PWREN high in dwmci_init().
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 commit 26c100232b09 "arm64: dts: rockchip: Fix sdmmc
access on rk3308-rock-s0 v1.1 boards" fixed this issue by adding a
vcc_sd regulator.
Include the new vcc_sd regulator in SPL and enable required Kconfig
options to set GPIO4_D6 low to fix reading sdmmc on v1.1 hw revision.
