ASoC: SOF: Intel: allow for coexistence between SOF and catpt drivers

Now that we have all the support needed for coexistence between ACPI
drivers for Broadwell, remove mutual exclusion in the Kconfig
file. The selection is done by playing with the snd_intel_dspcfg
module 'dsp_driver' parameter.

This adds support for Sound Open Firmware for Intel(R) platforms
using the Broadwell processors.
This option is mutually exclusive with the Haswell/Broadwell legacy
driver. If you want to enable SOF on Broadwell you need to deselect
the legacy driver first.
SOF does not fully support Broadwell yet, so this option is not
recommended for distros. At some point all legacy drivers will be
deprecated but not before all userspace firmware/topology/UCM files
are made available to downstream distros.
This option can coexist in the same build with the default 'catpt'
driver.
Existing firmware/topology binaries and UCM configurations typically
located in the root file system are already compatible with both SOF
or catpt drivers.
SOF does not fully support Broadwell and has limitations related to
DMA and suspend-resume, this is not a recommended option for
distributions.
Say Y if you want to enable SOF on Broadwell.
If unsure select "N".
