[PATCH 12/23] ASoC: Intel: sof_da7219: support MAX98357A on glk boards

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

From: Brent Lu <brent.lu@xxxxxxxxx>

For glk boards, MAX98357A speaker amplifier is supported by machine
driver bxt_da7219_max98357a with sound card name glkda7219max. Use
same name for backward compatibility with existing devices on market.
