dt-bindings: PCI: fu740-pci: fix missing clock-names
The commit b92225b034c0 ("dt-bindings: PCI: designware: Fix 'unevaluatedProperties' warnings") removed the clock-names property as a requirement and from the example as it triggered unevaluatedProperty warnings. dtbs_check was not able to pick up on this at the time, but now can: arch/riscv/boot/dts/sifive/hifive-unmatched-a00.dtb: pcie@e00000000: Unevaluated properties are not allowed ('clock-names' was unexpected) From schema: linux/Documentation/devicetree/bindings/pci/sifive,fu740-pcie.yaml The property was already in use by the FU740 DTS and the clock must be enabled. The Linux and FreeBSD drivers require the property to enable the clocks correctly Re-add the property and its "clocks" dependency, while making it required.
