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.

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.

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
