[Impact]
With the current default kernel config, the SND_SOC_SOF_BROADWELL_SUPPORT
is set to Y, then it will make the legacy intel soc driver fail, and
moreover the current sof driver can't support broadwell well, as a
result, many broadwell computers with I2S codec can't support sound anymore.

[Fix]
Intel submitted a patch, it will make those two kconfig options exclusive,
and the legacy soc's option has higher priority, if both of them are
enabled, sof's option will be disabled.

[Test Case]
Build the kernel and check the debian/build/$buidling_dir/.config,  the
SND_SOC_SOF_BROADWELL_SUPPORT is disabled.

[Regression Risk]
Low, so far, the sof driver can't support broadwell machine well, so
there is no machine use this driver yet.
