For K3 SoCs, ti-cpufreq depends on k3-socinfo to provide SoC revision
information via soc_device_match(). If ti-cpufreq probes before
k3-socinfo, soc_device_match() returns NULL, causing incorrect 
revision detection and OPP table initialization failures.

Add EPROBE_DEFER handling in ti-cpufreq when soc_device_match() fails
for K3 SoCs, ensuring k3-socinfo probes first.

Add device link support via a new DT property "ti,soc-info" in CPU
OPP tables. Device links prevent unbinding k3-socinfo while
ti-cpufreq is using it.

EPROBE_DEFER handles first-boot probe ordering, while device links
provide runtime dependency management.

For backward compatibility, the DT property is optional.
