Tegra already supports the common clock framework, but had issues:
1) The clock driver was located in arch/arm/mach-tegra/ rather than
drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.
