From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>
The commit in the fixes tag removed the clock-names property from the
SiFive FU740 PCI Controller dt-binding, but it was already in the dts
for the FU740. dtbs_check was not able to pick up on this at the time
but v2022.08 of dt-schema 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 Linux driver does not use this property, but outside of the kernel
this property may have users. Re-add the property and its "clocks"
dependency.
Fixes: b92225b034c0 ("dt-bindings: PCI: designware: Fix 'unevaluatedProperties' warnings")

I went back and forth on removing the property from the dts, but this
seems like the change that is more conservative..
