Russell King 56949d414a ARM: udelay: prevent math rounding resulting in short udelays 
We perform the microseconds to loops calculation using a number of
multiplies and shift rights.  Each shift right rounds down the
resulting value, which can result in delays shorter than requested.
Ensure that we always round up.
