The iCLKIP clock is used to drive the VGA pixel clock on the PCH. In order to do so, it must be programmed to properly do the clock ticks according to the divisor, phase direction, phase increments and a special auxiliary divisor for 20MHz clock. v2: calculate divisor values directly instead of relying on a table. v3: merged a fix from Ben to properly check for invalid divider values.
