Subject: [PATCH v4 3/4] drm/panel: jd9365da: Support for kd101ne3-40ti MIPI-DSI panel.

The K&d kd101ne3-40ti is a 10.1" WXGA TFT-LCD panel, use
jd9365da controller,which fits in nicely with the existing
panel-jadard-jd9365da-h3 driver.Hence,we add a new compatible
with panel specific config.

Although they have the same control IC, the two panels are different,
and the timing will be slightly different, so we added some variables
in struct jadard_panel_desc to control the timing

Changes between V4 and V3:
-  1. Use mipi_dsi_msleep.
-  2. Adjust the ".clock" assignment format.
-  3. Adjust "compatible" positions to keep the list sorted.

V3:https://lore.kernel.org/all/20240614145510.22965-4-lvzhaoxiong@huaqin.corp-partner.google.com/

Changes between V3 and V2:
-  1. Give up creating a new driver and re-add K&d kd101ne3-40ti 
-     configuration to the panel-jadard-jd9365da-h3.c driver.

V2:https://lore.kernel.org/all/20240601084528.22502-3-lvzhaoxiong@huaqin.corp-partner.google.com/

Changes between V2 and V1:
-  1. Use the new mipi_dsi_dcs_write_seq_multi() function.
-  2. Modify Move mipi_dsi_dcs_set_display_off() and mipi_dsi_dcs_enter_sleep_mode() to disable(),
-  and drop kingdisplay_panel_enter_sleep_mode().
-  3. If prepare fails, disable GPIO before regulators.
-  4. This function drm_connector_set_panel_orientation() is no longer used. Delete it.
-  5. Drop ".shutdown = kingdisplay_panel_shutdown".
