ASoC: meson: Constify static snd_pcm_hardware

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Static 'struct snd_pcm_hardware' is not modified by the driver and its
copy is passed to the core, so it can be made const for increased code
safety.
