    imx-drm: match ipu_di_signal_cfg's clk_pol with its description.

    According to the datasheet, setting the di0_polarity_disp_clk
    field in the GENERAL di register sets the output clock polarity
    to active high.

The ipuv3 makes heavy use of video encoders internally to the SoC but
also external encoders are common. Switch to VPL support to be able
to handle these properly.

ARM: move DMA alloc functions to dma.h ...

This better separates the DMA from the MMU functionality.

Also move all drivers that only depends on asm/mmu.h for the alloc
functions over to the common header.

ARM: change dma_alloc/free_coherent to match other architectures ...

As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM
we define DMA_ADDRESS_BROKEN to mark them. In order to use them on
other architectures with a different mapping they need proper fixing.
