 * Notice:
 * 1. rk3399-roc-pc-plus is powered by dc_12v directly.
 * 2. rk3399-roc-pc-plus has only vcc_bus_typec0 in schematic, which is coresponding
 *    to vcc_vbus_typec1 in rk3399-roc-pc.
 *    For simplicity, reserve the node name of vcc_vbus_typec1.
 * 3. vcc5v0_host is actually 2 regulators (host0, 1) controlled by the same gpio.
