Description

arm64: rockchip: rk808: Only init regulator not enabled

If a regulator is already enabled, do not set its value to the minimum
supported on the board.
This fixes booting on rock64 where we set some regulator to the minimal value
while the IPs needs more based on what the bootloader configured.
