ARM: tegra: Rearrange subsystem initialization order

Fuses must be initialized before clocks, so clocks can
determine the maximum cpu frequency.  Clocks must be
initialized before DMA, so DMA can enable the clock.
Once DMA is initialized, all fuses accesses must go
through DMA to avoid a hardware bug.
