All of the secondary CPUs are forced in to light sleep mode, but we were
missing the same initialization for the boot CPU. This resulted in
inconsistent sleep modes depending on which CPU we were on, confusing the
idle loop when not polling.

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.

are const).

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!
