Zong Li 0493692b40 dt-bindings: change the macro name of prci in header files and example
We currently change the macro name for fu540 and fu740 by adding the
prefix respectively, the dt-bindings should be modified as well.

description:
Should be something similar to "sifive,<chip>-uart"
for the UART as integrated on a particular chip,
and "sifive,uart<version>" for the general UART IP
block programming model.
UART HDL that corresponds to the IP block version
