Channels allocated via dma_get_any_slave_channel were not increasing
the counter tracking private allocations.  When these channels were
released, privatecnt may erroneously fall to zero.  The DMA device
would then lose its DMA_PRIVATE cap and fail to allocate future private
channels (via private_candidate) as any allocations still outstanding
would incorrectly be seen as public allocations.

bcm2835-mmc/sdhost: of_dma_request_slave_channel isn't exported

of_dma_request_slave_channel isn't an exported function, so can't be
used from within a module. Replace with dma_request_slave_channel,
which calls the of_ variant but IS exported.

Make the bcm2835-mmc driver available for use on ARCH_BCM2835.

Some options in bcm2835_defconfig are now the default and
some have changed. Update to keep functionality.

No longer available: SCSI_MULTI_LUN and RESOURCE_COUNTERS.

Remove the dmaman device since the dmaengine now handles
the legacy API manager.

Remove dma.c driver which is now merged with bcm2708-dmaengine.

Signed-off-by: Noralf Trønnes <noralf@tronnes.org>

Merge the legacy DMA API driver with bcm2708-dmaengine.
This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
driver is also needed).

Changes to the dma.c code:
- Use BIT() macro.
- Cutdown some comments to one line.
- Add mutex to vc_dmaman and use this, since the dev lock is locked
  during probing of the engine part.
- Add global g_dmaman variable since drvdata is used by the engine part.
- Restructure for readability:
  vc_dmaman_chan_alloc()
  vc_dmaman_chan_free()
  bcm_dma_chan_free()
- Restructure bcm_dma_chan_alloc() to simplify error handling.
- Use device irq resources instead of hardcoded bcm_dma_irqs table.
- Remove dev_dmaman_register() and code it directly.
- Remove dev_dmaman_deregister() and code it directly.
- Simplify bcm_dmaman_probe() using devm_* functions.
- Get dmachans from DT if available.
- Keep 'dma.dmachans' module argument name for backwards compatibility.

Make it available on ARCH_BCM2835 as well.

Prepare for merging of the legacy DMA API arch driver dma.c
with bcm2708-dmaengine by adding memory and irq resources both
to platform file device and Device Tree node.
Don't use BCM_DMAMAN_DRIVER_NAME so we don't have to include mach/dma.h

BCM2835 has two SD card interfaces. This driver uses the other one.

The obsolete WIRELESS_EXT configuration is used
by the old Realtek code and is needed for AP support.

The HiFiBerry Digi driver did not signal the sample rate in the SPDIF status bits.
While this is optional, some DACs and receivers do not accept this signal. This patch
adds the sample rate bits in the SPDIF status block.
