dt-bindings: hwmon: ti,ina2xx: Add ti,alert-polarity-active-high property 



Add a property to the binding to configure the Alert Polarity.
Alert pin is asserted based on the value of Alert Polarity bit of
Mask/Enable register. It is by default 0 which means Alert pin is
configured to be active low open collector. Value of 1 maps to
Inverted (active high open collector).
