regulator: arizona-ldo1: Use PROBE_FORCE_SYNCHRONOUS

Restore synchronous probing for Arizona regulators because otherwise
the main MFD driver will not find its core supplies.

As these regulators are built into the CODEC and typically have no DT
representation the regulator framework is unaware of their existence
until the driver probes. These means the probing of the driver needs to
be synchronous to ensure the regulators are not substitued for the dummy
later when the users request them.
