Add regulator driver for the device AWINIC AW37503 which is single
inductor - dual output power supply device. AW37503 device is
designed to support general positive/negative driven applications
like TFT display panels.
AW37503 regulator driver supports to enable/disable and set voltage
on its output.

I think that these 3 lines could be outside of the loop.
