ARM64: zynqmp: Support for multiple PM IDs assigned to a PM domain

Previously, it was assumed that there is a 1:1 mapping between
PM ID defined in the platform firmware and a PM domain. However, there
can be a situation where multiple PM IDs belong to a single PM domain
(e.g. PM IDs for GPU and two pixel processors correspond to a single
PM domain).

This patch adds support for assigning more than one PM ID to
a single PM domain.

Updated documentation accordingly.

Assigned pixel processors PM IDs to GPU PM domain.
