[PATCH v2] ASoC: Intel: bxt-da7219-max98357a: support MAX98390 speaker amp

[Brent Lu <brent.lu@intel.com>]

Support MAX98390 speaker amplifier on cometlake platform. Driver now
detects amplifier type in the probe function and installs corresponding
controls and DAPM widgets/routes in the late_probe function.
