Subject: [PATCH 01/12] spi: dt-bindings: introduce the ``fifo-depth`` property
There are instances of the same IP that are configured by the integrator
with different FIFO depths. Introduce the fifo-depth property to allow
such nodes to specify their FIFO depth.
We haven't seen SPI IPs with different FIFO depths for RX and TX, thus
introduce a single property.
