On CHRP machines we are supposed to call into firmware (RTAS)
periodically, to give it a chance to check for errors and other
events. Under ppc we had some special code in timer_interrupt
to do this, but that didn't get transferred over to arch/powerpc.
Instead, we use an array of timer_list structs, one per CPU,
and use add_timer_on to make sure each one gets called on the
appropriate CPU.
With this we can remove the heartbeat_* elements of the ppc_md
struct.

This implements a nvram acccess method, similar to
arch/ppc64/kernel/pSeries_nvram.c tested on CHRP B50.
