[ion] 23692: - Fix some bugs in clock.S - Enable clock.S versions of KeUpdateSystem/RunTime and export them properly. - Enable systimer.S to call into kernel's KeUpdateSystemTime. - Enable Hal's Clock Interrupt during Phase 1. - Remove most of the code that was still left in irq.c - Only one large problem remains now, which is the spurious firing of the clock interrupt before we're ready to handle it... I will try to fix this today.

New Revision: 23692
URL: http://svn.reactos.org/svn/reactos?rev=23692&view=rev
Log:
- Fix some bugs in clock.S
- Enable clock.S versions of KeUpdateSystem/RunTime and export them properly.
- Enable systimer.S to call into kernel's KeUpdateSystemTime.
- Enable Hal's Clock Interrupt during Phase 1.
- Remove most of the code that was still left in irq.c
- Only one large problem remains now, which is the spurious firing of the clock interrupt
before we're ready to handle it... I will try to fix this today.
