Subject: [PATCH] dt-bindings: serial: Add a new compatible string for UMS9632

Due to the platform's new project uart ip upgrade,
the new project's timeout interrupt needs to use bit17
while other projects' timeout interrupt needs to use
bit13, using private data to adapt and be compatible
with all projects. The sc9632-uart is incompatible
with sc9836-uart, Add sc9632-uart dedicated compatible
for representing uart of the new project UMS9632 SoC.
