ASoC: meson: axg-fifo: add NO_PERIOD_WAKEUP support

On the AXG family, the fifo irq is not necessary for the HW to operate.
It is just used to notify that a period has elapsed. If userpace does not
care for these wakeups (such as pipewire), we are just wasting CPU cycles.

Add support for NO_PERIOD_WAKEUP and disable irq when they are no needed.

ASoC: meson: axg-fifo: relax period size constraints

Now that the fifo depths and thresholds are properly in the axg-fifo
driver, we can relax the constraints on period. As long as the period is a
multiple of the fifo burst size (8 bytes) things should be OK.

ASoC: meson: axg-fifo: improve depth handling

Let the fifo driver parse the fifo depth from DT. Eventually all DT should
have this property. Until it is actually the case, default to 256 bytes if
the property is missing. 256 bytes is the size of the smallest fifo on the
supported SoCs.

On the supported SoC, fifo A is usually bigger than the other ones. With
depth known, we can improve the usage of the fifo and adapt the setup of
request threshold.

ASoC: meson: axg-fifo: fix fifo threshold setup

On TODDR sm1, the fifo threshold register field is slightly different
compared to the other SoCs. This leads to the fifo A being flushed to
memory every 8kB. If the period is smaller than that, several periods
are pushed to memory and notified at once. This is not ideal.

Fix the register field update. With this, the fifos are flushed every
128B. We could still do better, like adapt the threshold depending on
the period size, but at least it consistent across the different
SoC/fifos

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

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.
