ASoC: meson: axg-fifo: add g12a support
The g12a fifos gained the ability to set the initial address of the
pointer within the buffer, instead of defaulting to the buffer start
address.

It is not very useful to us (yet) but we need to put a copy the buffer
start address in the related register for the fifo to work properly on the
g12a SoC family

fba3b09f18 ASoC: meson: Drop superfluous PCM preallocation error checks
snd_pcm_lib_preallocate_pages() and co always succeed, so the error
check is simply redundant.  Drop it.

ASoC: meson: use IRQ_RETVAL in the fifo irq handler
Use IRQ_RETVAL instead of the open coded ternary operation.

ASoC: meson: add axg fifo base driver
Amlogic's axg SoCs have two types of fifos which are the memory
interfaces of the audio subsystem. FRDDR provides the playback
interface while TODDR provides the capture interface.

The way these fifos operate is very similar. Only a few settings
are specific to each.

They implement the same pcm driver here and the specifics of each
will be dealt with the related DAI driver.
