f5ac658d16 imx233: normalise clkctrl 
The clkctrl functions were becoming a mess. Normalise the names,
get rid of the xtal derived as special case and use the same
interface.

ca83b558df imx233: fix potential hbus dividor settings + doc 
HBUS uses the same field for integer and fractional dividers, the
choice is made by a bit. Make sure both are changed together,
otherwise this could result in the wrong divider to be used and in
HBUS freq to be too low or too high (very bad).

cd7a478ec1 imx233: enable PLL on startup 
Implement PLL enabling/disable and unconditionally power the PLL
on startup. This is needed at least on the Zen X-Fi2.

0d78dd170d imx233: user __FIELD_SET to set the clock divisors 
The clock divisors must *NEVER* be 0, first clearing then setting is thus undefined.
