[POWERPC] Small cleanup of EFIKA platform
The efika platform used three files efika-pci.c efika-setup.c and a 2 line efika.h to link the two. The total of code in those is really not much and therefore, I think they're better merged in a single file. There is absolutely _no_code_change_ at all, just merged the files.
