While we list the "IRQ status *and acknowledge*" registers as volatile
in the MFD description, they are missing from the writable range array,
so acknowledging any interrupts was met with an -EIO error.
This error propagates up, leading to the whole AXP717 driver failing to
probe, which is fatal to most systems using this PMIC, since most
peripherals refer one of the PMIC voltage rails.
This wasn't noticed on the initial submission, since the interrupt was
completely missing at this point, but the DTs now merged describe the
interrupt, creating the problem.
Add the five registers that hold those bits to the writable array.
This fixes the boot on the Anbernic systems using the AXP717 PMIC.
Fixes:

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 reStructuredText 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.
