ASoC: SOF: nocodec: fix card prefix

The "sof-" prefix is added by the code, don't add it to the card name.
This helps make sure the card is named "sof-nocodec" instead of
"sof-sof-nocodec", e.g.

root@ubilinux4:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sofnocodec [sof-nocodec], device 0: Port0 (*) []
  Subdevices: 1/1
  Subdevice #0: subdevice #0
