ARM: Tegra: DMA: Fail safe if initialization fails
tegra_dma_init currently simply bails out early if any initialization fails.
This skips various data-structure initialization. In turn, this means that
tegra_dma_allocate_channel can still hand out channels. In this case, when
tegra_dma_free_channel is called, which calls tegra_dma_cancel, the walking
on ch->list will OOPS since the list's next/prev pointers may still be
NULL.
To solve this, add an explicit "initialized" flag, only set this once _init
has fully completed successfully, and have _allocate_channel refuse to hand
out channels if this is not set.
While at it, simplify _init:
* Remove redundant memsets
* Use bitmap_fill to mark all channels as in-use up-front, and remove
some now-redundant bitmap initialization loops.
* Only mark a channel as free once all channel-related initialization has
completed.
Finally, the successful exit path from _init always has ret==0, so just
hard-code that return. The error path still returns ret.

ARM: tegra: Move tegra_common_init to tegra_init_early
The reason is that tegra_init_early_ calls tegra_dma_init which calls
request_threaded_irq, which fails since the IRQ hasn't yet been marked
valid; that only happens in tegra_init_irq, which gets called after
tegra_init_early.
This used to work OK, since tegra_init_early was tegra_common_init, which
got called after tegra_init_irq, basically from the beginning of
tegra_harmony_init.
Solve this by converting tegra_dma_init to a postcore_initcall. This makes
it execute late enough that IRQs are marked valid, and avoids having to
add it back to every machine's init function.
