We add a helper function to detect amplifier number according to device instance in ACPI table so the SOF_MAX98390_TWEETER_SPEAKER_PRESENT flag and a dmi quirk for 4-amplifier configuration could be safely removed.

Also refactor the max_98390_hw_params() function to use an array to handle the TDM parameter.

Amplifier number detection and TDM parameter are tested on two Chromebooks. One with 2 MAX98390 and one with 4 MAX98390 amplifier.

V2 Changes: - fix some typos in cover letter - use for_each_acpi_dev_match() macro to simplify the codec - use 'unsign int' for codec number variable

V3 Changes: - replace pr_err() with dev_err()
