[PATCH v6 6/8] dt-bindings: serial: snps-dw-apb-uart: add Allwinner A523

[James Hilliard]

The A523 UART integration has different FIFO depths across its controllers
and reports each controller's depth in the FIFO Clock Control register.
Its receive thresholds are fractions of that depth, and its optional
register layout differs from the generic DesignWare integration.

Add a compatible for this integration, also used by A527 and T527, with
snps,dw-apb-uart as a fallback.
