hwmon: (pmbus) Add mutex to regulator ops
On PMBUS devices with multiple pages, the regulator ops need to be
protected with the update mutex. This prevents accidentally changing
the page in a separate thread while operating on the PMBUS_OPERATION
register.
Tested on Infineon xdpe11280 while a separate thread polls for sensor
data.
