dt-bindings: usb: qcom,snps-dwc3: Add constraints for SM4250

The qcom,sm4250-dwc3 is already documented in top level part, but it
misses specific constraints for clocks.  The SoC is derivative of SM6115
(or vice versa), so the interrupts part is incorrectly placed and should
be same as for SM6115.
