MMC driver probe will abort for DT case because of failed
platform_get_resource_byname() lookup. Fix it by skipping resource
byname lookup for device tree build.
Issue is hidden because hwmod popullates the IO resources which
helps to succeed platform_get_resource_byname(
Convert dmaengine channel requests to use
dma_request_slave_channel_compat(). This supports platforms booting

Changes since v7:
- Dropped dmaengine compat() patch. It is upstream.
- Submitted edma_alloc_slot() error checking bug fix separately,
now a dependency
- Fixed bisect issues due to 3/10 hunks that went into 1/10
- Fixed incorrect IS_ERRVALUE() use in 3/10
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.
