hwmon: (pmbus) Always call _pmbus_read_byte in core driver
Always call _pmbus_read_byte() instead of pmbus_read_byte() in PMBus core driver. With this change, device specific read functions can be implemented for all registers. Since the device specific read_byte function is now always called, we need to be more careful with page validations. Only fail if the passed page number is larger than 0, since -1 means "current page".
