#1459344 — [PATCH v2] clocksource/drivers/time-armada-370-xp: Fix the clock reference

While converting the init function to return an error, the wrong clock
was get. This lead to wrong clock rate and slow down the kernel. For
example, before the patch a typical boot was around 15s after it was 1
minute slower.
