mfd: axp20x: Mark the AXP809's die-temperature ADC reading 'volatile'
The AXP809 provides an internal temperature sensor, measuring the
PMIC's die temperature and exporting this reading in an ADC register.
This change splits the AXP809 register definition from the AXP22x
to allow higher-layer (e.g. hwmon) drivers to read the current
temperature of the chip.
