rockchip: Port IO-domain driver for RK3568 from linux
Port the Rockchip IO-domain driver for RK3568 from linux.
The driver auto probe after bind to configure IO-domain based on the
regulator voltage. Compared to the linux driver this driver is not
notified about regulator voltage changes and only configure IO-domain
based on the initial voltage autoset by the regulator.
It is not recommended to enable MMC_IO_VOLTAGE or the mmc signal voltage
and IO-domain may end up out of sync.
Based on the linux commit 28b05a64e47c ("soc: rockchip: io-domain: add
rk3568 support").
