zhouwl 764634ffd0 ASoC: aw882xx: set speaker default impedance value 
According to Astro audio calibration statistical data in ODM
Ontim factory, set 7.3 as speaker default impedance value.
If aw_cali.bin is not exist, use 7.3ohm for aw882xx speaker
protection algorithm.

NO_PROP_NEEDED: aw882xx doesn't use in bq-shm2018 products.
