There is no "opp-hz-real" property at all defined in the bindings and
new DTS is not allowed to bring undocumented properties. Fix dtbs_check
warnings like:
imx95-15x15-evk-pcie0-ep.dtb: opp-500000000: opp-hz-real: b'\x00\x00\x00\x00\x1d\xcde\x00' is not of type 'object', 'integer', 'array', 'boolean', 'null'
