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.
