hrtimer: Get rid of the resolution field in hrtimer_clock_base
commit
398ca17fb54b212cdc9da7ff4a17a35c48dd2103 upstream.
The field has no value because all clock bases have the same
resolution. The resolution only changes when we switch to high
resolution timer mode. We can evaluate that from a single static
variable as well. In the !HIGHRES case its simply a constant.
Export the variable, so we can simplify the usage sites.
