doc: bindings: power: act8945a-charger: Update properties.

Due the driver improvements, update the properties,
 - Remove "active-semi,check-battery-temperature" property.
 - Add the properties, "active-semi,irq_gpio"
   and "active-semi,lbo-gpios".
 - As act8945a-charger is regarded as a sub-device, update
   the compatible and examples.

 Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
 
 Required properties:
- - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
+ - compatible: "active-semi,act8945a-charger".
  - active-semi,chglev-gpios: charge current level phandle with args
    as described in ../gpio/gpio.txt.
+ - active-semi,lbo-gpios: specify the low battery voltage detect phandle
+   with args as as described in ../gpio/gpio.txt.
+ - interrupts: <a b> where a is the interrupt number and b is a
+   field that represents an encoding of the sense and level
+   information for the interrupt.
+ - interrupt-parent: the phandle for the interrupt controller that
+   services interrupts for this device.
 
 Optional properties:
- - active-semi,check-battery-temperature: boolean to check the battery
-   temperature or not.
  - active-semi,input-voltage-threshold-microvolt: unit: mV;
    Specifies the charger's input over-voltage threshold value;
    The value can be: 6600, 7000, 7500, 8000; default: 6600
