Revert "hwmon: (pmbus) Add regulator supply into macro"
This reverts commit 54cc3dbfc10dc3db7cb1cf49aee4477a8398fbde.
Zev Weiss reports that the reverted patch may cause a regulator
undercount. Here is his report:
... having regulator-dummy set as a supply on my PMBus regulators
(instead of having them as their own top-level regulators without
an upstream supply) leads to enable-count underflow errors when
disabling them:
# echo 0 > /sys/bus/platform/devices/efuse01/state
[ 906.094477] regulator-dummy: Underflow of regulator enable count
[ 906.100563] Failed to disable vout: -EINVAL
[ 136.992676] reg-userspace-consumer efuse01: Failed to configure state: -22
Zev reports that reverting the patch fixes the problem. So let's do that
for now.
