power_supply: Add min/max alert properties for CAPACITY, TEMP, TEMP_AMBIENT
Minimum and maximum alerts on power supply properties will help or allow
the user space to "proactively" create policies like connect/disconnect
charger or stop/start the user apps based on capacity or temperature
parameters.
These parameters can be used to avoid unnecessary polling from user space
and even from kernel space if the underlying HW can support INT triggers
(ex: max17042/47).
This patch adds the following power supply alert type properties:
CAPACITY_ALERT_MIN
CAPACITY_ALERT_MAX
TEMP_ALERT_MIN
TEMP_ALERT_MAX
TEMP_AMBIENT_ALERT_MIN
TEMP_AMBIENT_ALERT_MAX
