Add a Synopsys Designware MIPI DSI host DRM bridge driver for their
DSI2 host controller, based on the Rockchip version from the driver
rockchip/dw-mipi-dsi2.c in their vendor-kernel with phy & bridge APIs.
While the driver is heavily modelled after the previous IP, the register
set of this DSI2 controller is completely different and there are also
additional properties like the variable-width phy interface.

The Synopsys DesignWare HDMI 2.1 Quad-Pixel (QP) TX Controller IP
supports the following features, among others:
* Fixed Rate Link (FRL)
* Display Stream Compression (DSC)
* 4K@120Hz and 8K@60Hz video modes
* Variable Refresh Rate (VRR) including Quick Media Switching (QMS), aka
Cinema VRR
* Fast Vactive (FVA), aka Quick Frame Transport (QFT)
* SCDC I2C DDC access
* TMDS Scrambler enabling 2160p@60Hz with RGB/YCbCr4:4:4
* YCbCr4:2:0 enabling 2160p@60Hz at lower HDMI link speeds
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)
Add library containing common helpers to enable basic support, i.e. RGB
output up to 4K@30Hz, without audio, CEC or any HDMI 2.1 specific
features.

Move DRM's HMDI helpers into the display/ subdirectoy and add it
to DRM's display helpers. Update all affected drivers. No functional
changes.
The HDMI helpers were implemented in the EDID and connector code, but
are actually unrelated. With the move to the display-helper library, we
can remove the dependency on drm_edid.{c,h} in some driver's HDMI source
files.
Several of the HDMI helpers remain in EDID code because both share parts
of their implementation internally. With better refractoring of the EDID
code, those HDMI helpers could be moved into the display-helper library
as well.
v3:
* fix Kconfig dependencies (Javier)
v2:
* reduce HDMI helpers to avoid exporting functions (Jani)
* fix include statements (Jani, Javier)
* update Kconfig symbols

The dw-hdmi driver switched to regmap-mmio, but lacks the dependency in
Kconfig. This can result in compilation breakages. Fix it by selecting
REGMAP_MMIO.

The driver is already made of 5 separate source files. Move it to a
newly created directory named synopsys where more Synopsys bridge
drivers can be added later (for the DisplayPort controller for
instance).
