[PATCH] PCI: imx6: fix building against host-common

[PATCH] PCI: imx6: fix building against host-common

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

When CONFIG_PCI_HOST_COMMON is set to =m, the i.MX6 PCIe driver
fails to link. This can happen when only i.MX endpoint mode is
enabled but not host mode, which would indirectly enable the
host-common driver itself.

ld.lld: error: undefined symbol: pci_host_common_parse_ports
>>> referenced by pci-imx6.c
>>>               drivers/pci/controller/dwc/pci-imx6.o:(imx_pcie_host_init) in archive vmlinux.a

ld.lld: error: undefined symbol: pci_host_common_delete_ports

Select the common module from the endpoint support directly.
