[PATCH 2/2] regulator: fixed: Set PROBE_PREFER_ASYNCHRONOUS

[Douglas Anderson]

As of commit 218320fec294 ("regulator: core: Fix off-on-delay-us for
always-on/boot-on regulators"), we now might have a big delay during
probe of fixed regulators. That can have a significant boot speed
impact. Let's mitigate this by preferring async probe for fixed
regulators. The regulator framework itself has no issues with
regulators probing in an asynchronous way. The fixed regulator driver
is fairly straightforward and also has no issues.
