mfd: db8500-prcmu: Update stored DSI PLL divider value
Previously the DSI PLL divider rate was initialised statically and assumed to be 1. Before the common clock framework was enabled for ux500, a call to clk_set_rate() would always update the HW registers no matter what the current setting was. This patch makes sure the actual hw settings and the sw assumed settings are matched.
