[PATCH] uml: timer initialization cleanup

This cleans up the mess that is the timer initialization.  There used to be
two timer handlers - one that basically ran during delay loop calibration and
one that handled the timer afterwards.  There were also two sets of timer
initialization code - one that starts in user code and calls into the kernel
side of the house, and one that starts in kernel code and calls user code.

This eliminates one timer handler and consolidates the two sets of
initialization code.
