Cleanup regulator shell to use strtol() over atoi(), as strtol features
error detection. Remove device_is_ready() checks, and replace them with
NULL checks as device_get_binding() calls device_is_ready() interally

Drop the async enable function. This feature is rarely/never used,
complicates driver design, and doesn't really follow the sync/async API
design/naming used in other areas. In the future we can introduce
regulator_enable_async if needed, with support from the driver class (no
onoff). Note that drivers like PCA9420 did not implement any
asynchronous behavior. regulator-fixed implemented in the past
asynchronous behavior using work queues, an overkill for most GPIO
driven regulators. Let's keep things simple for now and extend the API
when needed, based on specific usecases.
In the current implementation, reference counting is managed by the
driver class. \isr-ok attribute is dropped, since calls are potentially
blocking. Note that drivers like PCA9420 already violated such rule.

The regulator API supports all voltage/current ops, so there's no need
to guard them under "PMIC". If a particular driver doesn't support the
operations it will just return -ENOSYS and the command will fail.

In Zephyr all regulator APIs are consumer APIs. There's no point in
adding a separate header file. Our current implementation is also
inconsistent with Linux, where enable/disable are also part of the
consumer.h API.

Add shell for interacting with regulator devices, to enable
users to test power management settings quickly and verify that their
regulator is functioning as expected. Also allows users to interact with
regulator PMIC devices
