PCI: dwc: all: Split struct pcie_port into host-only and core structures

Browse Source 
Keep only the host-specific members in struct pcie_port and move the common
members (i.e common to both host and endpoint) to struct dw_pcie.  This is
in preparation for adding endpoint mode support to designware driver.

While at that also fix checkpatch warnings.
