Remove the compatible "synopsys,dw-mipi-dsi" added in U-Boot
(it don't exist in Linux kernel binding); it is only used
to bind the generic synopsys UCLASS_DSI_HOST "dw_mipi_dsi" to
the driver "stm32-display-dsi" UCLASS_VIDEO_BRIDGE
This binding is done in Linux kernel drivers without compatible
(dw_mipi_dsi_bind() is called in bind of driver, for example in
drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c).
This patch does the same in U-Boot driver, the STM32 driver
calls during its bind the function device_bind_driver_to_node
to bind the generic driver "dw_mipi_dsi" at the same address.
This patch reduces the device tree differences
between Linux kernel and U-Boot for stm32mp1 platform.
Tested with v2020.01-rc1 on STM32MP157C-EV1 and STM32MP157C-DK2.
The dependency of driver is clearer and the probe order is guaranteed.

The new class dsi host allows the management of the bridge DPI to DSI.
This bridge is embedded in the chipset mp1 (come from synopsys company).

As for Audio codec IC, HDMI IC is not "IO safe".
HDMI regulators (v3v3 and v1v2) must be enabled to allow
I2C1 bus usage. HDMI IC must be under reset during power up
and keep HDMI and AUDIO devices in reset while they are not
used in U-Boot to keep them in low power mode
(each device can be kept in reset independently keeping their
power supplies ON until kernel).

This patch synchronizes U-boot DT with kernel one
This is based on https://patchwork.kernel.org/cover/10797115/
This patch adds initial support of STM32MP157 discovery boards:
- Add support of stm32mp157a discovery1 board (part number: STM32MP157A-DK1).
This board embeds a STM32MP157a SOC with AC package (TFBGA361, 148 ios)
and 512MB of DDR3. Several connections are available on this boards:
4*USB2.0, 1*USB2.0 typeC, SDcard, RJ45, HDMI, Arduino connector, ...
- Add support of stm32mp157c discovery2 board (part number: STM32MP157C-DK2).
This board is a "super-set" of stm32mp157a-dk1. A display panel (otm8009a)
and Murata wifi/BT combo is added.
