regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers between 4.19 and 5.4

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 4.19 but did exist in Linux 5.4.

regulator: Use of_property_read_bool() for boolean properties

It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties.
Convert reading boolean properties to to of_property_read_bool().

regulator: remove locking around regulator_notifier_call_chain()

regulator_notifier_call_chain() doesn't need rdev lock and rdev's
existence is assumed in the code anyway. Remove the locks from drivers.

regulator: stpmic1_regulator: Properly document 'struct stpmic1_regulator_cfg'

In kerneldoc format, data structures have to start with 'struct'
else the kerneldoc tooling/parsers/validators get confused.

Fixes the following W=1 kernel build warning:

drivers/regulator/stpmic1_regulator.c:25: warning: cannot understand function prototype: 'struct stpmic1_regulator_cfg '

regulator: stpmic1: Remove regul_id and *regmap from struct stpmic1_regulator

At the context with *rdev available, regulator core provides

So no need to store them in struct stpmic1_regulator.
