ASoC: Intel: sof_sdw: starts non sdw BE id with the highest sdw BE id

The soundwire links do not have their IDs as consecutive numbers, thus
the last link might have lower be_id than the previous one and this
leads to id collision with non SDW links.

For example,
create dai link SDW0-Playback-SimpleJack, id 0
create dai link SDW0-Capture-SmartMic, id 4
create dai link SDW0-Capture-SimpleJack, id 1
create dai link SDW2-Playback-SmartAmp, id 2
create dai link SDW2-Capture-SmartAmp, id 3
create dai link iDisp1, id 4
create dai link iDisp2, id 5
create dai link iDisp3, id 6
