Commit 52060836f79 ("dt-bindings: omap-rng: Document SafeXcel IP-76
device variant") update the omap_rng Device Tree binding to add support
for the IP-76 variation of the IP. As part of this change, a "clocks"
property was added, but is indicated as "Required", while it is in fact
"Optional": some SoCs do not require a clock for this IP block.
