dt-bindings: fsi: Document the FSI controller common properties

2024-07-09T13:40:17+00:00

Since there are multiple FSI controllers documented, the common
properties should be documented separately and then referenced
from the specific controller documentation. Add bus-frequency for
the FSI bus and CFAM local bus frequencies. Add interrupt
controller properties.

2024-07-09T13:40:17+00:00

The FSI2SPI bridge has several SPI controllers behind it, which
should be documented. Also, therefore the node needs to specify
address and size cells.
