Subject: [PATCH 3/3] dt-bindings: cpufreq: cpufreq-qcom-hw: Narrow
 properties on SDX75, SA8775p and SM8650

Add SDX75 and SA8775p compatibles to respective if:then: blocks to
narrow their properties and add a new section for SM8650 with four 'reg'
and 'interrupts' (top-level already allows four).

SA8755p DTS comes without interrupts, but only because they might not
be available for OS under given firmware.
