[ 23/70] ASoC: wm8994: Ensure there are enough BCLKs for four channels

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mark Brown <broonie@xxxxxxxxxxxxxxxxxxxxxxxxxxx>

commit b8edf3e5522735c8ce78b81845f7a1a2d4a08626 upstream.

Otherwise if someone tries to use all four channels on AIF1 with the
device in master mode we won't be able to clock out all the data.
