Revert "sh: Bump the earlytimer bits back to time_init()."
This reverts commit 1d29ebebcb951ab6b04d22807cafb24b893310a2.

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

PC is at trace_hardirqs_on_caller+0x48/0x10c
PR is at trace_hardirqs_on_caller+0x3c/0x10c

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