PPC: booke timers

Browse source 
While working on the emulation of the freescale p2010 (e500v2) I realized that
there's no implementation of booke's timers features. Currently mpc8544 uses
ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for
example booke uses different SPR).
