video: stm32: remove the compatible "synopsys, dw-mipi-dsi" support 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.
