Colin Cross 0cf6230af9 ARM: tegra: Move tegra_common_init to tegra_init_early
Move tegra_common_init to tegra_init_early, and set it
as the init_early entry in the machine struct.
Initializes the clocks earlier so that timers can enable
their clocks.

Also reorders the members in the Harmony and Trimslice
boards' machine structs to match the order they are
called in.
