[PATCH] arm64: dts: meson: shorten audio card names for alsa compatibility

This patch shortens all audio card model names by dropping the SoC prefix
(for conformity) and rewording those that are still longer than alsa's 15
character name limit [0] to avoid userspace config issues.

I've been experimenting with alsa conf files to ensure alsa handles
multi-channel audio properly (else channels are messed up) and it's
been bugging me why an Odroid N2 showed surroundXX devices (defined in
a common alsa conf) while a VIM3 only showed sysdefault devices. The
eureka moment is discovering alsa enforces a 15-character limit on
model names, so G12B-ODROID-N2 (14) works while longer names like
G12B-KHADAS-VIM3 (16) truncate to e.g. G12B-KHADAS-VIM causing mismatch
with the strings alsa-lib matches conf(s) against.

VIM3:~ # cat /proc/asound/cards
 0 [G12BKHADASVIM3 ]: G12B-KHADAS-VIM - G12B-KHADAS-VIM3
                      G12B-KHADAS-VIM3

I'm using aliases.conf with alsa-lib to map 20+ card names back to
two confs so I _could_ just map the truncated names, but this is not
obvious for users and other maintainers so the better solution is
shortening the names.
