[PATCH 3/5] PCI: mvebu: Remove custom mvebu_pci_host_probe() function

[Pali Rohár]

Now after pci_ioremap_io() usage was replaced by devm_pci_remap_iospace()
function, there is no need to use custom mvebu_pci_host_probe() function.
Current implementation of mvebu_pci_host_probe() is same as standard PCI
core functionn pci_host_probe(). So replace mvebu_pci_host_probe() call by
pci_host_probe() and remove custom mvebu_pci_host_probe() function.
