Add bindings and DRM panel driver for EBBG FT8719 6.18" 2246x1080 DSI video mode panel, which can be found on some Xiaomi Poco F1 phones. The panel's backlight is managed through QCOM WLED driver.
The driver is built using linux-mdss-dsi-panel-driver-generator[1], and additionally support for handling regulators and linking external backlight is added.

Changes in v4: (Linus Walleij's Suggestion) - Introduce mipi_dsi_dcs_write_seq macro in include/drm/drm_mipi_dsi.h - Remove the driver specific dsi_dcs_write_seq macro - Use the newly introduced mipi_dsi_dcs_write_seq macro instead
Changes in v3: (Mostly Linus Walleij's Suggestions) - Removed ctx->prepared state variable as it's handled by the core - Print error in dsi_dcs_write_seq macro if it fails to write - Removed magic power on sequences as panel works fine without them
Changes in v2: (Krzysztof Kozlowski's Suggestions) - dt-bindings: specify maxItems for reg - dt-bindings: cleanup and simplify the panel properties - dt-bindings: in example change "|+" to "|' and "dsi0" to "dsi"
