ASoC: amd: acp: fix card name length warning in SOF SoundWire machine driver

Browse Source 
The ALSA snd_card driver[] field is 16 bytes (including the NUL
terminator), leaving 15 usable characters. The SOF framework
prepends a "sof-" prefix when registering the card, so
card->name = "amd-soundwire" becomes driver name "sof-amd-soundwire"
which is 17 characters and overflows the driver[16] buffer, triggering
a kernel warning.

Fix by shortening the card name to "amd-sdw"; the resulting driver
name "sof-amd-sdw" fits within the 15-character limit.
