Add PowerPC decrementer clock event driver.
Every effort has been made to support the different implementations of the decrementer: the classic one (with 970 series variation), 40x and Book E specific ones.
I had to make CONFIG_GENERIC_CLOCKEVENTS option selectable for the compatibility reasons -- this option is not compatible with the PPC64 deterministic time accounting.
Thanks to Daniel Walker and Thomas Gleixner for the suggestions they made...

Thomas, that part of the ppc-clockevents.patch (part of the -rt patch) is
now broken, it makes CONFIG_MAX_ZONEORDER dependent on
!CONFIG_GENERIC_CLOCKEVENTS -- this is probably due to patch's fuzzy logic.
Do I need to send a patch to fix this?
WBR, Sergei
