[PATCH] ASoC: wm8962: Correct the bit offset to enable mono speaker output

[Nicolin Chen]

As WM8962 datasheet describes for SPK_MONO bit of R51: When SPK_MONO
is set to '1', both speakers output the signal from the left channel.

So for mono speaker widget, we shall enable Left Channel whose enable
bit is 6 instead of 7 (Right Channel).

This patches just simply corrects the bit offset.

@Peter
I cced you just to let you know that I'm merging your fix to upstream.
And because you patch can't be applied to the upstream tree directly,
I used my own commit with your signed-off. Thank you for the fix.
