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

The mutex for the regulator_dev must be controlled by the caller of
the regulator_notifier_call_chain(), as described in the comment
for that function.
Failure to mutex lock and unlock surrounding the notifier call results
in a kernel WARN_ON_ONCE() which will dump a backtrace for the
regulator_notifier_call_chain() when that function call is first made.
The mutex can be controlled using the regulator_lock/unlock() API.

Fix off-by-one while iterating current_limits array.
The valid index should be 0 ~ n_current_limits -1.

Declare regulator_ops structure as const as it is only stored in the ops
field of a regulator_desc structure. This field is of type const, so
regulator_ops structures having this property can be made const too.

Three files are modified, the driver, header file and the binding document.
Updates for the regulator source file include and .of_match_table entry
and node match checking in the probe() function for a compatible pv88080
silicon type. A new "HVBUCK" is added in source file and added
regsiter definition in header file for pv88080 bb silicion.
The binding documentation changes have been made to reflect these updates.

This is the driver for the Powerventure PV88080 BUCKs regulator.
It communicates via an I2C bus to the device.
