regulator: core: Add new API to poll for error conditions
Regulator consumers can receive event notifications when
errors are reported to the driver, but currently, there is
no way for a regulator consumer to know when the error is over.
To allow a regulator consumer to poll for error conditions
add a new API: regulator_get_error_flags.
