This shouldn't be per compatible really. The definition here is wrong
too. You should know the max baud for the chip based on the compatible.
This property is for when the max is less than the max of either the
chip or host UART.

I have enabled max-speed in probe for compatible "qcom,wcn3990-bt", so
it under the specific compatible string.
will update definition.
