hwmon: (pmbus) Introduce and use write_byte_data callback
Some of the pmbus core functions uses pmbus_write_byte_data, which does
not support driver callbacks for chip specific write operations. This
could potentially influence some specific regulator chips that for
example need a time delay before each data access.
Lets add support for driver callback with _pmbus_write_byte_data.
