Subject: [PATCH 0/2] PCI: mvebu: Add support for unbinding and unloading driver

This patch series add support for unbinding device from pci-mvebu driver,
allow to compile pci-mvebu.c as kernel module pci-mvebu.ko and allow to
rmmod this module.

This patch series depends on another patch series which converts
pci-mvebu.c driver to use devm_pci_remap_iospace() function:

"arm: ioremap: Remove pci_ioremap_io() and mvebu_pci_host_probe()":
https://lore.kernel.org/linux-pci/20211124154116.916-1-pali@kernel.org/

Without usage of devm_pci_remap_iospace() it is not possible to bind
device to pci-mvebu driver again after unbinding it.

Tested on Turris Omnia - Armada 385 board.
