soundwire: intel: set dev_num_ida_min 



The allowed values for SoundWire device numbers are between 1 and 11
(inclusive). HDaudio/iDISP codecs typically use SDI values 0..3
(inclusive). To allow for a unique peripheral SDI/dev_number across
HDaudio and SoundWire buses, we set the minimum base to 4. This still
allows for 8 SoundWire peripherals in the system, currently more than
needed in actual products.
