[PATCH] clk: iproc: round clock rate to the closest

[Ray Jui]

From: Lori Hikichi <lhiki...@broadcom.com>

Change from 'DIV_ROUND_UP' to 'DIV_ROUND_CLOSEST' when calculating the
clock divisor in the iProc ASIU clock driver to allow to get to the
closest clock rate.

Fixes: 5fe225c105fd ("clk: iproc: add initial common clock support")
