[PATCH 3.2] mfd: Update wm8994 active device checks for WM1811

[Mark Brown <broonie@opensource.wolfsonmicro.com>]

This didn't go in as part of the original MFD patch for WM1811 due to
cross tree issues.

This is essentially a bugfix for 3.2 - suspend is likely to not work
well without it, it wasn't merged as part of the original patch set due
to cross tree issues.
