[PATCH v12 08/17] dt-bindings: fix sifive clint compatible string

[Damien Le Moal]

Fix the Sifive clint compatible string definition to make the value
"sifive,fu540-c000-clint" optional, allowing a DT to specify only
"sifive,clint0" for its generic implementation without any tweak.
With this change, a Sifive clint node can now be defined as explained
in the compatible string description.
