[Audio] Change the Audience FW selection mechanism

[Audio] Change the Audience FW selection mechanism

BZ: 25136

We need to control which firmware is loaded by the driver.

The es305b driver uses the platform data to know which firmware
should be loaded.
The FW selection is choosen on the user side. The solution is to
extend the BOOTUP_INIT ioctl command to handle the filename as
argument comming from the user space.
