Thanks ! Setting CLKDIVN after the PLLs have settled looks a bit
scary to me. This is a change from 1:3:6 down to 1:4:8, so we'd
run with HCLK = 133MHz and PCLK = 66.7MHz for a while.

So I've moved the CLKDIVN update before the delay. Let's see if
it still works ... yeah !

before: FCLK = 211 MHz, HCLK = 70 MHz, PCLK = 35 MHz, UCLK = 48 MHz
after:  FCLK = 400 MHz, HCLK = 100 MHz, PCLK = 50 MHz, UCLK = 48 MHz

Committed as r3786.

Thanks,
- Werner
