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.

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

Instead:
The commit b92225b034c0 ("dt-bindings: PCI: designware: Fix

No, it did not do it... At least I cannot see it. Where is the removal
exactly in that patch? The commit removed clock-names from required, not
from properties.

 but it was already in the dts
