ALSA: hda/tas2781: Add speaker id check for ASUS projects
Add speaker id check by gpio in ACPI for ASUS projects.
In other vendors, speaker id was checked by BIOS, and was applied in
last bit of subsys id, so we can load corresponding firmware binary file
for its speaker by subsys id.
But in ASUS project, the firmware binary name will be appended an extra
number to tell the speakers from different vendors. And this single digit
come from gpio level of speaker id in BIOS.
