While it is possible to hook other CRTC implementations into imx-drm
in practice there are none yet and the option to disable ipuv3-crtc
support has been hidden for a long time.
Now that the imx-drm-core has learned to deal with some of the
specifics of IPUv3 there is a cyclic dependency between both parts.
To get rid of this and to decimate the Kconfig maze a bit, simply
merge both parts into one module.

the original imx hdmi driver is under drm/imx/,
which depends on imx-drm, so move the imx hdmi
driver out to drm/bridge and rename it to dw_hdmi

IMX6 and Rockchip RK3288 and JZ4780 (Ingenic Xburst/MIPS)
use the interface compatible Designware HDMI IP, but they
also have some lightly differences, such as phy pll configuration,
register width, 4K support, clk useage, and the crtc mux configuration
is also platform specific.
To reuse the imx hdmi driver, convert it to drm_bridge
handle encoder in imx-hdmi_pltfm.c, as most of the encoder
operation are platform specific such as crtc select and
panel format set
This patch depends on Russell King's patch:

The imx-drm driver was put into staging mostly for the following reasons,
all of which have been addressed or superseded:
- convert the irq driver to use linear irq domains
- work out the device tree bindings, this lead to the common of_graph
bindings being used
- factor out common helper functions, this mostly resulted in the
component framework and drm of_graph helpers.
Before adding new fixes, and certainly before adding new features,
move it into its proper place below drivers/gpu/drm.
