Subject: [PATCH] regulator: wm8994: Use PROBE_FORCE_SYNCHRONOUS

Restore synchronous probing for wm8994 regulators because otherwise the
sound device is never initialized on Exynos5250-based Arndale board.

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