This converts all of arch/arm/mach-davinci to the common clock framework.
The clock drivers from clock.c and psc.c have been moved to drivers/clk,
so these files are removed.

There is one subtle change in the clock trees. AUX, BPDIV and OSCDIV
clocks now have "ref_clk" as a parent instead of the PLL clock. These
clocks are part of the PLL's MMIO block, but they bypass the PLL and
therefore it makes more sense to have "ref_clk" as their parent since
"ref_clk" is the input clock of the PLL.

CONFIG_DAVINCI_RESET_CLOCKS is removed since the common clock frameworks
takes care of disabling unused clocks.

Known issue: This breaks CPU frequency scaling on da850.

This functionality needs to be restored as part of this series since we
cannot commit anything with regressions.


Do you have a suggestion on how to accomplish this? I don't have a board for testing, so I don't have a way of knowing if my changes will work or not.


Also, the order of #includes are cleaned up in files while we are touching
this code.

This is a pretty huge patch again and I hope it can be broken down.
Ideally one per SoC converted and then the unused code removal.


Will do.
