mfd: Initialise WM831x IRQ masks on chip even if interrupts not in use

Ensure that the hardware has interrupts masked if we are not using
the interrupt controller on the WM831x by initialising the masks
before we check for the setup data required for the IRQ line. This
avoids signalling an unused IRQ line and improves the robustness
of checks that the IRQ is in use.
