ASoC: OMAP: Fix DSP_B format in OMAP McBSP DAI driver
The DSP format wasn't still correct in OMAP McBSP DAI even after the commit
bd25867a6cbe7a00ef7dbe8d9ddebc91b00b9b3f.
Thanks to Peter Ujfalusi <peter.ujfalusi@nokia.com> for noticing and being
part of the fix. Now the FS length definition is more clear by defining
it with FWID(0).
