clk: iproc: Separate status and control variables

Some PLLs have separate registers for Status and Control. The means the pll_base needs to be split into 2 new variables, so that those PLLs can specify device tree registers for those independently. Also, add a new driver flag to identify this presence of the split, and let the driver know that additional registers need to be used.
