spi: dt-bindings: spi-mux: Drop "spi-max-frequency" as required

Browse Source 
There's little reason to require the SPI mux to define a maximum bus
frequency as the muxing is just the chip select and devices still define
their maximum freq. In fact, several users don't set "spi-max-frequency"
which caused warnings.
