[PATCH AUTOSEL 6.14 382/642] PCI/pwrctrl: Move pci_pwrctrl_unregister() to pci_destroy_dev()

[Sasha Levin <sashal@kernel.org>]

From: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org>

[ Upstream commit 2d923930f2e3fe1ecf060169f57980da819a191f ]

The PCI core will try to access the devices even after pci_stop_dev()
for things like Data Object Exchange (DOE), ASPM, etc.

So, move pci_pwrctrl_unregister() to the near end of pci_destroy_dev()
to make sure that the devices are powered down only after the PCI core
is done with them.
