[PATCH] edb93xx: Avoid stack usage in early_udelay()

[Matthias Kaehlcke]

edb93xx: The purpose of early_udelay() is to provide delay functionality in the
early board setup, when the stack isn't set up yet. With some compiler versions
the current implementation makes use of the stack and ends up crashing. Fix this
by removing an explicit division from early_udelay()
