Commit 0881841f7e introduced a regression by inverting a test check
after calling clocksource_mmio_init(). That results on the system to
hang at boot time.
Fix it by inverting the test again.

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.

Sigma Designs Tango platforms provide a 27 MHz crystal oscillator.
Use it for clocksource, sched_clock, and delay_timer.
