[PATCH] iio: adc: axp288: Add TS bias override for Haier HV103H

[Vladyslav Ivashchenko <cactucatu4eckuu@gmail.com>]

The Haier HV103H firmware configures the AXP288 TS pin bias
current to 60 uA. This causes the battery temperature reading to
cross the charging temperature threshold under load, incorrectly
stopping battery charging.

Setting the TS bias current to 80 uA fixes the temperature
measurement and prevents charging from being incorrectly disabled.

Add a DMI quirk to use the 80 uA TS bias current on the Haier
HV103H.
