[hrtimer] Change resolution storage to ktime_t format
Change the storage format of the per base resolution to ktime_t to make it easier accessible in the hrtimers code. Change the resolution from (NSEC_PER_SEC/HZ) to TICK_NSEC as Roman pointed out. TICK_NSEC is closer to the real resolution. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
