[POWERPC] Made FSL Book-E PMC support more generic
Some of the more recent e300 cores have the same performance monitor implementation as the e500. e300 isn't book-e, so the name isn't really appropriate. In preparation for e300 support, rename a bunch of fsl_booke things to say fsl_emb (Freescale Embedded Performance Monitors).
