After this series, the plan is to convert the last in-tree user
of the private EDMA API (davinci-pcm/mcasp) and then eliminate
the private EDMA API by folding its functionality into
drivers/dma/edma.c.

Fix build on OMAP, the irqs are undefined on AM33xx.
These error interrupt handlers were hardcoded as disabled
so since they are unused code, simply remove them.

anner. Ideally, we would
want the implementation to observe the ti,deassert-hard-reset property
and use that in omap_hwmod.c:_enable() *after* the module is unidled
and the clocks active. However, this is actually functional for purposes
of getting the uio_pruss driver up and running.

L3RAM (shared SRAM) is needed for use by several drivers.
This creates a genalloc pool and a hook for the platform code
to provide the struct gen_pool * in platform data.

It's generally good practice to try the PPC development trees before
reporting PPC kernel bugs. http://www.fsmlabs.com/linuxppcbk.html
