ARM: dts: mstar: unitv2: Link cpu to core regulator
This commit adds a reference to the core voltage regulator as the CPU
supply, ensuring the regulator is correctly described as feeding the CPU.

[Severity: Low]
Since the SSD202D is a dual-core SoC and both Cortex-A7 cores share the same
physical voltage domain fed by reg_vcc_core, should there also be a matching
cpu-supply property added for &cpu1?
While the cpufreq-dt driver might infer the shared supply via the opp-shared
property when processing cpu0, would adding it for cpu1 provide a more
complete OS-agnostic hardware description for the device tree?
