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".
