Kernel: Create the time page region before initializing the timers

Browse source 
We were unconditionally trying to update it in the interrupt, which
would depend on the timer interrupt not being received too soon after
the timers are initialized (before the time page was initialized),
which was the case when using HPET timers via the ACPI tables, but not
when using the PIT when ACPI was disabled.
