Palmas series device like TPS65913, TPS80036 supports the backup battery
for powering the RTC when no other energy source is available.
The backup battery is optional, connected to the VBACKUP pin, and can be
nonrechargeable or rechargeable. The rechargeable battery can be charged
from the system supply using the backup battery charger.
Add support for enabling charging of this backup battery. Also add the DT
binding document and the new properties to have this support.

Enable dev as wakeup device before calling rtc_device_register(), so that
it can create the "wakealarm" sysfs.

Add of_device_id table for Palma RTC to be enable the driver from DT file.
The driver can be registered from DT file as:

:::::::::::
palmas_rtc {
compatible = "ti,palmas-rtc";
interrupt-parent = <&palmas>;
interrupts = <8 0>;
};
};

devm_rtc_device_register() is device managed and makes cleanup
paths simpler.
Also, use devm_request_threaded_irq() to make cleanup paths more simple.
