asoc: codecs: Change WSA config params acquisition

Update WSA rload, system gain, bat_cfg to get from wsa_macro device tree.
WSA Bat_cfg change to read from VPHX_SYS_EN_STATUS reg.
Add device tree parsing for these params in WSA macro
and WSA driver.
Remove machine driver method of sending the parameters.
Add default_dev_mode (spkr vs rcv) from device tree for WSA.
Move code from spkr event to userspace controls or probe.
Change system_gain and affected params when switching between
dev_modes.
These changes simplify configuration data and code and allow
more registers to be written during bootup or before playback.
