Subject: [PATCH] regulator: qcom-rpmh: Revert "regulator: qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS"

This reverts commit 58973046c1bf ("regulator: qcom-rpmh: Use
PROBE_FORCE_SYNCHRONOUS"). Further digging into the problems that
prompted the us to switch to synchronous probe showed that the root
cause was a missing "rootwait" in the kernel command line
arguments. Let's reinstate asynchronous probe.

Fixes: 58973046c1bf ("regulator: qcom-rpmh: Use PROBE_FORCE_SYNCHRONOUS")
