bd9e5ca89e arm: move __mmu_cache_flush to bare_init section
Instead of having seperate cache flush functions in the startup code
we want to call the generic functions. To accomplish this they have
to be in the bare_init section.

Some devices, especially the ones doing DMA should be disabled before
giving control to an OS. We take the simple approach here: Just shutdown
the devices in the reverse order they were activated.
