[PATCH v2 1/5] mfd: axp20x: AXP717: Fix missing IRQ status registers range

While we list the "IRQ status *and acknowledge*" registers as volatile,
they are missing from the writable range array, so acknowledging any
interrupts was met with an -EIO error.

Add the five registers that hold those bits to the writable array.
