This MIPS specific thing has been moved to be done when PCI code call the 'pcibios_root_bridge_prepare()' function which has been implemented for MIPS ralink mt7621 platform. Hence, remove MIPS specific code from driver code. After this change there is also no need to add any MIPS specific includes to avoid some errors reported by Kernet Test Robot with W=1 builds.
