driver: switch to new sdc_support_channel_sounding function

In order to allow users to configure their own antenna switch logic, we
needed to update the sdc_support_channel_sounding function. This should
change the default logic to use the new function.

Also fixed a bug in the kconfig dependency to compile with the cs
antenna switch logic.
