spi: dt-bindings: cdns,qspi-nor: make cdns,fifo-depth optional

Make cdns,fifo-depth devicetree property optional.
Value can be detected at runtime.

Upper SRAMPARTITION register bits are read-only. Procedure to find FIFO
depth is therefore to write 0xFFFFFFFF and read back to get amount of
writeable bits.
