Handle shared reset GPIO for WSA883x speakers

Merge series from Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>:

On some Qualcomm platforms such as QCS6490-RB3Gen2, the multiple
WSA8830/WSA8835 speakers share a common reset (shutdown) GPIO.
To handle such cases, use the reset controller framework along with the
"reset-gpio" driver.

Tested on:
