[PATCH 2/3] dt-bindings: serial: snps-dw-apb-uart: Add Allwinner A733

[Vinicius Pedrosa]

The Allwinner A733 UART is a DesignWare APB UART with two SoC-specific
differences. Its baud clock is the bus clock gate, which can't change
rate, and offset 0xc0 holds an RS485 control register instead of DLF.

Add a SoC-specific compatible, with "snps,dw-apb-uart" as the fallback.
