The driver as originally submitted accidentally relied on Android having
run before and Android having unmasked the 2nd level IRQ-mask for the
charger IRQ. This worked since these are PMIC registers which are only
reset when the battery is fully drained or disconnected.
Fix the charger IRQ no longer working after loss of battery power by
properly setting the 2nd level IRQ-mask for the charger IRQ.
Note this removes the need to enable/disable our parent IRQ which just
sets the mask bit in the 1st level IRQ-mask register, setting one of
the 2 level masks is enough to stop the IRQ from getting reported.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
