davinci: add SRAM allocator
Provide a generic SRAM allocator using genalloc, and vaguely modeled after what AVR32 uses. This builds on top of the static CPU mapping set up in the previous patch, and returns DMA mappings as requested (if possible). Compared to its OMAP cousin, there's no current support for (currently non-existent) DaVinci power management code running in SRAM; and this has ways to deallocate, instead of being allocate-only. The initial user of this should probably be the audio code, because EDMA from DDR is subject to various dropouts on at least DM355 and DM6446 chips.
