Subject: [PATCH] rtc: Use genirq directly in rtc-wm831x

Now that the WM831x core uses genirq for the IRQ controller there is
no need to use the WM831x-specific wrappers to request interrupts so
convert to use genirq directly.

Also use more meaningful strings to make /proc/interrupts more readily
legible.
