Zhaoxiong Lv June 1, 2024, 8:45 a.m. UTC 
This Starry panel has the same timing as the Kingdisplay panel,
so add starry configuration in the Kingdisplay driver.

Chage since V2:

-  Add compatible for Starry er88577 in panel-kingdisplay-kd101ne3 drivers.

Do these two panels share the same driver IC? Programming sequences do
not seem common, so it might be better to have a separate driver for
this panel.

Most of the comments from the patch 2 apply:
- drop conditions
- use mipi_dsi_dcs_set_display_on_multi(),
  mipi_dsi_dcs_exit_sleep_mode_multi() and mipi_dsi_msleep().

hi Dmitry

These two panels are not the same IC but their timing is the same,
only the init cmd and panel parameters are different, so I made it
compatible on the kingdisplay driver.

Similar to this driver:  panel-boe-tv101wum-nl6.c

thanks
