Revert "hwmon: (pmbus) Add regulator supply into macro" 

This reverts commit 54cc3dbfc1.

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.
