ASoC: codecs: aw88261: Add firmware-name support

Since the aw88261_acf.bin file appears to be device-specific, add
firmware-name support so that devicetree users can point to a
device-specific path to not conflict with other devices that might also
ship a aw88261_acf.bin.

Read the "firmware-name" property if available, and otherwise fall back
to the generic name.
