[PATCH] Time: i386 Conversion - part 3: Enable Generic Timekeeping

This converts the i386 arch to use the generic timeofday subsystem.  It
enabled the GENERIC_TIME option, disables the timer_opts code and other arch
specific timekeeping code and reworks the delay code.

While this patch enables the generic timekeeping, please note that this patch
does not provide any i386 clocksource.  Thus only the jiffies clocksource will
be available.  To get full replacements for the code being disabled here, the
timeofday-clocks-i386 patch will needed.

- *        on failure.
- * @mark_offset: called by the timer interrupt.
- * @get_offset:  called by gettimeofday(). Returns the number of microseconds
- *               since the last timer interupt.
- * @monotonic_clock: returns the number of nanoseconds since the init of the
