Patrick Rudolph bfe602d9a3 regulator: core: Prevent integer underflow 
[ Upstream commit 8d8e165920 ]

By using a ratio of delay to poll_enabled_time that is not integer
time_remaining underflows and does not exit the loop as expected.
As delay could be derived from DT and poll_enabled_time is defined
in the driver this can easily happen.

Use a signed iterator to make sure that the loop exits once
the remaining time is negative.
