Implement driver_name to provide an alternative to card_name for userspace configuration of Amlogic audio cards.

The meson AIU/AXG drivers currently require alsa confs based on the board model name which is unique to each board. This is very flexible for audio use-cases, but not very maintainable for distros with a single use-case that need to support a large number of different Amlogic boards. Using a driver name to match the card conf instead of card/model name reduces the number of confs needed in the LibreELEC (Kodi) distro from 41 to 2.
