[PATCH 2/4] ASoC: intel: sof_da7219_max98373: Add speaker switch

[Pierre-Louis Bossart]

From: Yong Zhi <yong.zhi at intel.com>

Add "Spk Switch" and associated widget, route to max98360a
speaker amp for power saving, also remove the speaker_amp_init()
callback with complete separated tables for max98373 and max98360a.
