[PATCH 5/9] [v10, 5/9] drm/panel: Add Boe Himax8279d MIPI-DSI LCD panel

[Jerry Han]

Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI
panel.

V5:
- Add the information of the reviewer (Sam)
- Delete unnecessary header files #include <linux/fb.h> (Sam)
- The config DRM_PANEL_BOE_HIMAX8279D appears twice. Drop one of them (Sam)
- ADD static, set_gpios function is not used outside this module (Sam)

V4:
- Frefix all function maes with boe_ (Sam)
- Fsed "enable_gpio" replace "reset_gpio", Make it look clearer (Sam)
- Sort include lines alphabetically (Sam)
- Fixed entries in the makefile must be sorted alphabetically (Sam)
- Add send_mipi_cmds function to avoid duplicating the code (Sam)
- Add the necessary delay(reset_delay_t5) between reset and sending
    the initialization command (Rock wang)

V3:
- Remove unnecessary delays in sending initialization commands (Jitao Shi)

V2:
- Use SPDX identifier (Sam)
- Use necessary header files replace drmP.h (Sam)
- Delete unnecessary header files #include <linux/err.h> (Sam)
- Specifies a GPIOs array to control the reset timing,
    instead of reading "dsi-reset-sequence" data from DTS (Sam)
- Delete backlight_disable() function when already disabled (Sam)
- Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam)
- Move the necessary data in the DTS to the current file,
    like porch, display_mode and Init code etc. (Sam)
- Add compatible device "boe,himax8279d10p" (Sam)

V1:
- Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI
    panel.
