Paul Mundt fc6191dd30 sh: Fix up clockevents broadcasting. 
This fixes up the clockevents broadcasting code as detailed in commit
ee348d5a1d ("[ARM] realview: fix broadcast
tick support"). This saves us from having to do strange ordering things
with the broadcast clockevent device, relying on the rating instead.

Rusty Russell e09377bae4 cpumask: Use accessors for cpu_*_mask: sh 
Use the accessors rather than frobbing bits directly (the new versions
are const).

Paul Mundt 71f0bdcab6 sh: smp: shove a cpu_relax() in the plat_start_cpu() busy loop. 
Without this, certain versions of GCC will happily optimize the entire
loop out.

Paul Mundt 1a442fe02d sh: Initial SH-X3 SMP support. 
This adds basic support for SH-X3 SMP (4 CPUs).

More IPI and cache debugging is necessary, mostly interfacing the
d-cache coherency and the I-cache broadcast invalidates. Only for
testing at present!
