ASoC: meson: cards: select SND_DYNAMIC_MINORS

Amlogic sound cards do create a lot of pcm interfaces, possibly more than
8. Some pcm interfaces are internal (like DPCM backends and c2c) and not
exposed to userspace.

Those interfaces still increase the number passed to snd_find_free_minor(),
which eventually exceeds 8 causing -EBUSY error on card registration if
CONFIG_SND_DYNAMIC_MINORS=n and the interface is exposed to userspace.

select CONFIG_SND_DYNAMIC_MINORS for Amlogic cards to avoid the problem.
