Updates of SoC-near drivers and other driver updates that makes more sense to
take through our tree. In this case it's involved:
- Some Davinci driver updates that has required corresponding platform code
changes (gpio mostly)
- CCI bindings and a few driver updates
- Marvell mvebu patches for PCI MSI support (could have gone through the PCI
tree for this release, but they were acked by Bjorn for 3.12 so we kept them
through arm-soc).
- Marvell dove switch-over to DT-based PCIe configuration
- Misc updates for Samsung platform dmaengine drivers

New and updated SoC support. Among the things new for this release are:
- More support for the AM33xx platforms from TI
- Tegra 124 support, and some updates to older tegra families as well
- imx cleanups and updates across the board
- A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM,
and turned out to be too broad a name. New name is ARCH_BCM_MOBILE.
- A whole bunch of updates and fixes for integrator, making the platform code
more modern and switches over to DT-only booting.
- Support for two new Renesas shmobile chipsets. Next up for them is more work
on consolidation instead of introduction of new non-multiplatform SoCs, we're
all looking forward to that!
- Misc cleanups for older Samsung platforms, some Allwinner updates, etc.

The dma mask is not configured in the current code.
This was triggered by soc-dmaengine-pcm which allocate the dma

register_platform_device_full() can setup the DMA mask provided the
appropriate member is set in struct platform_device_info. So lets
make that be the case. This avoids a direct reference to the DMA
masks by this driver.
While here, add the dma_set_mask_and_coherent() call which the DMA API
requires DMA-using drivers to call.

This code sequence:
if (!pdev->dev.dma_mask) {
pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask;
pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32);
}
bypasses the architectures check on the DMA mask. It can be replaced
with dma_coerce_mask_and_coherent(), avoiding the direct initialization
of this mask.

We can't use the %pa format for these because this relates to phys_addr_t,
and dma_addr_t can be a different size. So, fix these by converting them
to %llx and casting the dma_addr_t to always be unsigned long long.
While we're here, also use %zu for size_t.

davinci-pcm uses 16 as the no.of periods. With this, in EDMA we have to
allocate atleast 17 slots: 1 slot for channel, and 16 slots the periods.
Due to this, the MAX_NR_SG limitation causes problems, set it to 20 to make
cyclic DMA work when davinci-pcm is converted to use DMA Engine. Also add
a comment clarifying this.

PaRAM set calculation is abstracted into its own function to
enable better reuse for other DMA cases such as cyclic. We adapt
the Slave SG case to use the new function.
This provides a much cleaner abstraction to the internals of the
PaRAM set. However, any PaRAM attributes that are not common to
all DMA types must be set separately such as setting of interrupts.
This function takes care of the most-common attributes.
Also added comments clarifying A-sync case calculations.
