ASoC: amd: vangogh: Small code refactor

Small refactor of the code:
 - sort includes in alphabetical order
 - sort variables declarations by line length
 - remove unnecessary "struct snd_soc_card *card" lines
 - insert blank lines before return
 - break/unbreak some lines for better read
 - align defines
