The _PSD object (cf. ACPI 6.4, s8.4.5.5 _PSD (P-State Dependency)
allows to describe CPU's power state dependencies. Add a PsdToken
field to the CM_ARM_GICC_INFO object so that interdependent CPUs
can reference the same CM_ARM_PSD_INFO object.

Can you add something to the commit message about this bit?

This is actually a naming mistake in:
   [PATCH v1 06/11] DynamicTablesPkg: Add CM_ARM_PSD_INFO object
I will correct it it there, the change in this patch should be removed.

Regards,
Pierre
