[PATCH v5 2/4] PCI: host-generic: Rename and export gen_pci_init() to allow ECAM creation

[Mayank Rana <mayank.rana@oss.qualcomm.com>]

Rename gen_pci_init() API as pci_host_common_ecam_create() and export it to
create ECAM and initialized ECAM OPs from PCIe driver which don't have way
to populate driver_data as just ECAM ops.
