PCI: iproc: Convert to use the new ECAM constants

Browse source

Change interface of the function iproc_pcie_map_ep_cfg_reg() so that use
of PCI_SLOT() and PCI_FUNC() macros and most of the local ECAM-specific
constants can be dropped, and the new PCIE_ECAM_OFFSET() macro can be
used instead.  Use the ALIGN_DOWN() macro to ensure that PCI Express
ECAM offset is always 32 bit aligned.
