Hi all,

This is an attemp to add sdmmc UHS support to the ROC-RK3328-CC board.

It adds a new compatible `rockchip,rk3328-gpio-syscon10` to the gpio-syscon
driver,  so that a new gpio controller named `gpio_syscon10` can be defined
and used in the regulator-gpio. This regulator controls the signal voltage of the
sdmmc. It is essential for UHS support which requires 1.8V signal voltage.

  gpio: syscon: Add gpio-syscon for rk3328
  arm64: dts: rockchip: Add sdmmc UHS support for roc-rk3328-cc
