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

V9:
- Adjust init code, make the format more concise
- kill off default_off_cmds (Emil)
- use mipi_dsi_dcs_set_display_{on,off} in their enable/disable
    callbacks. (Emil)
- Adjusting the delay function (Emil)

V8:
- modify PARENTHESIS_ALIGNMENT format (Sam)
- use gpios are required API replace optional gpio API (Emil)

V7:
- Modify communication address

V6:
- Add the information of the reviewer
- Remove unnecessary delays, The udelay_range code gracefully returns
    without hitting the scheduler on a delay of 0. (Derek)
- Merge the same data structures, like display_mode and off_cmds (Derek)
- Optimize the processing of results returned by
    devm_gpiod_get_optional (Derek)

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.
