ASoC: atmel: Fixes for pinctrl

Browse Source 
Due to a series of problems with the handling of Atmel, a combination of
 making changes that make other branches instantly buggy and a general
 failure to deal with the resulting issues effectively, v3.8 Atmel audio
 currently won't work at all for DT boards without adding pinctrl
 definitions and a request for those.
