This commit introduces the clocks found in the Allwinner A33 CCU.
Since this SoC is very similar to the A23, and we share a significant share
of the DTSI, the clock IDs that are going to be used will also be shared
with the A23, hence the name of the various header files.

Some dividers might have a maximum value that is lower than the width of
the register.
Add a field to _ccu_div to handle those case properly. If the field is set
to 0, the code will assume that the maximum value is the maximum one that

Otherwise, we'll use whatever value has been set.

Most of the sun8i q8 boards have an SDIO wifi controller, on the
variants which use an USB wifi controller, this will result in a
couple of error msg-s in dmesg when proving the sdio bus and
an used mmc controller.
The best way to deal with wifi on this boards really is to simply
let the kernel auto-detect usb or sdio wifi controllers, so we
will just have to live with the few errors in dmesg.
This has been tested on a23 based q8 tablets with ESP8089, RTL8703AS and
RTL8189FTV wifi controllers.

On sunxi we support cpufreq by changing the clock rate of PLL-CPU.
It's possible the clock output of the PLL goes out of the CPU's
operational limits when the PLL's multipliers / dividers are changed
and it hasn't stabilized yet. This would result in the CPU hanging.
To circumvent this, we temporarily switch the CPU mux clock to another
stable clock before the rate change, and switch it back after the PLL
stabilizes. This is done with clk notifiers registered on the PLL.
This patch adds common functions for notifiers to reparent mux clocks.
