[PATCH] delay: Fix ndelay() spuriously treated as udelay()

[Frederic Weisbecker]

A recent rework on delay functions wrongly ended up calling __udelay()
instead of __ndelay() for nanosecond delays, increasing those by 1000.

As a result hangs have been observed on boot

Restore the right function calls.

Fixes: 19e2d91d8cb1 ("delay: Rework udelay and ndelay")
