PCI: Allow D3 for native hotplug-capable Root Ports on non-x86 platforms

Browse source

Commit eb3b5bf1a8 ("PCI: Whitelist native hotplug ports for runtime D3"),
prevented native hotplug-capable Root Ports from entering D3 citing issues
on old Intel SkyLake Xeon-SP platform.

But there is no reason to restrict D3 for native hotplug-capable Root Ports
on non-x86 platforms. We recently enabled D3 on non hotplug-capable Root
Ports on non-x86 platforms (specifically for DT platforms) in commit
a5fb3ff632 ("PCI: Allow PCI bridges to go to D3Hot on all non-x86"). So
do the same for native hotplug-capable Root Ports as well.
