[PATCH v2 1/2] dt-bindings: serial: snps-dw-apb-uart: Add Sophgo SG2044 uarts

[Inochi Amaoto]

The UART of SG2044 is modified version of the standard Synopsys
DesignWare UART. The UART on SG2044 relys on the internal divisor
and can not set right clock rate for the common bitrates.

Add compatibles string for the Sophgo SG2044 uarts.
