Removed unused clock_frequency member from struct cpudef which is get from FW_CFG and added bus-frequency property to complete the frequency properties. Also added tlb infos to cpudef (with values only for G4 currently as I have no data for other CPUs).

v2: Get bus-frequency from FW_CFG similarly to clock-frequency and tb-frequency (corresponding patch submitted to QEMU, already applied to ppc-next) v3: added definition of FW_CFG_PPC_BUSFREQ that was missed from v2
