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.

Now when driver uses devm_pci_remap_iospace() function, it is possible
implement ->remove() callback for unbinding device from driver.
Implement mvebu_pcie_remove() callback with proper cleanup phase, drop
driver's suppress_bind_attrs flag and switch type of CONFIG_PCI_MVEBU
option from bool to tristate.
This allows to compile pci-mvebu.c driver as loadable module pci-mvebu.ko
with ability to unload it.
