No, PCIe controller is not compatible with sm8550, we are just re using the boot

As we are going to use different dts schema for this controller we can't
really re-use
like how we have done in kaanapali case. kaanpali is reusing sm8550 schema, where
this controller can't use sm8550 schema, as some clocks are different.
