cf72965fbf Allwinner: Add A33 support 
Add basic support for A33/R16 that is enough to boot a kernel.
This adds the platform code, padconf data and the new clocks strings.

def44246f2 PLL3 have a fractional mode where an explicit frequency (297Mhz or 270) 
can be selected for it. If the desired frequency is one of those two, use
this mode instead of the integer one.
When calculating the PLL3 freq for the dotclock, check if it is a multiple
of the fracional frequencies.

51503e707b Upstream DTS provides PLL3 and PLL7 nodes (and their x2 form), 
so remove them from our DTS and adapt the code to handle them correctly.
This fix HDMI video on A20.

8c07f7653a The DTS may report fewer than 4 parents for a module clock. Avoid setting 
the module clock parent to an out-of-range index in these cases.

dac935533b EXTRES: Add OF node as argument to all <foo>_get_by_ofw_<bar>() functions. 
In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.
