On most of the Amlogic SoCs, the first UART controller in the "Everything-Else" power domain has 128bytes of RX & TX FIFO, so add an optional property to describe a different FIFO size from the other ports (64bytes).
This adds a property in the bindings, reads the property from the driver and updates the DT with the new property.
Changes since v2: - removed spurious blank line from bindings
Changes since v1: - switched to a more generic "fifo-size"
