clocksource/drivers/tango-xtal: Replace code by clocksource_mmio_init
The current code to initialize, register and read the clocksource is already factored out in mmio.c via the clocksource_mmio_init function. Factor out the code with the clocksource_mmio_init function. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org>
