ASoC: meson: Use managed DMA buffer allocation
Using a managed buffer will pre-allocate the buffer using
snd_pcm_lib_preallocate_pages() and automatically free it when the PCM is
destroyed.
In addition it will call snd_pcm_lib_malloc_pages() before the driver's
hw_params() callback and snd_pcm_lib_free_pages() after the driver's
hw_free() callback.
This slightly reduces the boilerplate code of the driver.
