hwmon: (pmbus) Move pec attribute to I2C device
Enabling and disabling PEC for PMBus devices is currently only supported with a debugfs attribute, which requires debugfs to be enabled and is thus less than perfect. Take the lm90 driver as example and add a 'pec' attribute to the I2C device if both the I2C adapter and the PMBus device support it. Remove the now obsolete 'pec' attribute from debugfs.
