[PATCH v2 5/6] arm64: dts: qcom: sm8550: Add missing CX power domain to GCC

[Neil Armstrong]

Unless CX is declared as the power-domain of GCC, votes (power and
performance) on the GDSCs it provides will not propagate to the CX,
which might result in under-voltage conditions.

Add the missing power-domains property to associate GCC with RPMHPD_CX.
