Min Yun 1a87dbca80 Change AP_POWER_STATE_REPORT's access property. 
Change AP_POWER_STATE_REPORT's access property from WRITE to READ_WRITE.
In Vehicle environment some hals communicate with external ecu,
so they must know the boot reason.
(Not only on, but DEEP_SLEEPY_EXIT, ON, CANCELD)
To handle this, AOSP provide CarPowerManager, but it use AIDL.
But, in treble, vendor process must communicate with system process via hidl.
So, vendor processes(almost hal), can't use CarPowerManager.
(Beside, CarPowerManager use /dev/binder but vendor process use /dev/vndbinder).
If hals subscribe AP_POWER_STATE_REPORT via vehicle hal,
they can handle the power state.

Autmotive HALs

Overview:

The automotive HAL tree is used by Android Automotive to discover and operate hardware specific to a car.

The HALs are not (yet) frozen, as the HAL definition is expected to evolve between Android releases.
