[alsa-devel] [PATCH 2/3] ASoC: OMAP: Fix setup of XCCR and RCCR registers in McBSP DAI

[Jarkko Nikula]

Commit ca6e2ce08679c094878d7f39a0349a7db1d13675 is setting up few XCCR and
RCCR bits for I2S and DPS_A formats. Part of the bits are already set
for all formats and I believe that XDISABLE and RDISABLE bits are
format independent.

As XCCR and RCCR are found only from OMAP2430 and OMAP34xx, I move setup
of XDISABLE and RDISABLE to where those cpu's are tested and remove format
dependent part for simplicity.
