dt-bindings: clock: sifive: add FU540-C000 PRCI clock constants
Add preprocessor macros for the important PRCI output clocks that are needed by both the FU540 PRCI driver and DT data. Details are available in the FU540 manual in Chapter 7 of https://static.dev.sifive.com/FU540-C000-v1.0.pdf Signed-off-by: Paul Walmsley <paul.walmsley@sifive.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
