The UART in the jz4725b works just like in the other JZ SoCs, so this
commit simply adds a new compatible string.

This shouldn't be necessary. Looks like it should be compatible with
ingenic,jz4740-uart.

Well, I'm confused, the driver already uses multiple compatible strings
for SoCs that
work the exact same, so that was wrong?

Not wrong, but not necessary. Given that the data was the same was the
clue telling me that they should be compatible.
