[PATCH v5 2/2] PCI / ACPI: Adjust comment about `HotPlugSupportInD3`

[Mario Limonciello <mario.limonciello@amd.com>]

The comments in `acpi_pci_bridge_d3` make an assertion that all devices
behind a PCIe root port that supports D3 also support D3.  This was
pointed out however that it's no guarantee but rather a reasonable
assumption for the ecosystem used for Thunderbolt and USB4.

Update the comment to use weaker language and clarifying this is an
assumption.
