[PATCH v3 3/8] clocksource: allow re-init for same clock

[Stefan Kerkmann <s.kerkmann@pengutronix.de>]

A clocksource might need to be re-initialized if fundamental parameter
changes e.g. the clock frequency. With the change the init sequence
which sets the global clocksource can be called unconditionally again
for the same clock.
