Subject: [PATCH v4 6/7] ARM: davinci: convert to common clock framework
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.
Also, the order of #includes are cleaned up in files while we are touching
this code.
