PCI: mvebu: Fix support for PCI_BRIDGE_CTL_BUS_RESET on emulated bridge
Hardware supports PCIe Hot Reset via PCIE_CTRL_OFF register. Use it for
implementing PCI_BRIDGE_CTL_BUS_RESET bit of PCI_BRIDGE_CONTROL register on
emulated bridge.
With this change the function pci_reset_secondary_bus() starts working and
can reset connected PCIe card.
