pci: pci_mvebu: Inline mvebu_pcie_port_parse_dt() function

Browse Source 
Function mvebu_pcie_port_parse_dt() is called only from
mvebu_pcie_of_to_plat() function. Both these function parse DT properties
required to setup mvebu pcie. So inline mvebu_pcie_port_parse_dt() function
into mvebu_pcie_of_to_plat() to have all code related to parsing DT
properties at one place.
