[PATCH 2/2] regulator: arizona-micsupp: Use PROBE_FORCE_SYNCHRONOUS

[Charles Keepax <ckeepax@opensource.cirrus.com>]

Restore synchronous probing for Arizona regulators as the main MFD
relies on the ordering of the devices probing.

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.

Fixes: 259b93b21a9f ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14")
