Grygorii Strashko b3be3f6a36 rtc: palmas: Drop IRQF_EARLY_RESUME flag
Palams RTC IRQ is nested threaded and wired to the Palmas inerrupt
controller. So, this flag is not required for nested irqs anymore,
since commit 3c646f2c6a ("genirq: Don't suspend nested_thread irqs
over system suspend") was merged.

Laxman Dewangan 666a584d3a drivers/rtc/rtc-palmas.c: support for backup battery charging
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.
