clocksource: TCLIB: Allow higher clock rates for clock events
As default the TCLIB uses the 32KiHz base clock rate for clock events. Add a compile time selection to allow higher clock resulution. Signed-off-by: Benedikt Spranger <b.spranger@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
