Thomas Gleixner 21d6d52a1b hrtimer: Get rid of softirq time
The softirq time field in the clock bases is an optimization from the
early days of hrtimers. It provides a coarse "jiffies" like time
mostly for self rearming timers.

But that comes with a price:
    - Larger code size
    - Extra storage space
    - Duplicated functions with really small differences
   
The benefit of this is optimization is marginal for contemporary
systems.

Consolidate everything on the high resolution timer
implementation. This makes further optimizations possible.

Text size reduction:
       x8664 -95, i386 -356, ARM -148, ARM64 -40, power64 -16
