Revert "sh: Bump the earlytimer bits back to time_init()." 



This reverts commit 1d29ebeb.

Bumping up the earlytimer initialization causes IRQs to be enabled too
early, which blows up lockdep:

...
NR_IRQS:256 nr_irqs:256
------------[ cut here ]------------
Badness at kernel/lockdep.c:2128

PC is at trace_hardirqs_on_caller+0x48/0x10c

Revert it back to late_time_init time, which fixes up lockdep.
