This method will set the desired voltaged based on values in the DTS.
It will not enable the regulator, this is the job of either a consumer
or regnode_set_constraint SYSINIT if the regulator is boot_on or always_on.

arm64: rockchip: rk_i2c: Bump to DELAY to 1000
In polling mode with use DELAY to wait for interrupts. The value was
too low for RK3328.
r358279:
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.
