From: Chris Morgan <macromorgan@xxxxxxxxxxx>
Add the vendor specific boolean property of x-powers,no-thermistor.
This property optionally describes hardware where no thermistor is
present on the battery and is specific to the AXP717. In rare
circumstances this value can be set incorrectly in the efuse of the
PMIC, and if it is not hard-coded the device will fail to charge.
