[PATCH v1 1/2] drm/panel: jd9365da: Move the sending location of the 11/29 command

[Zhaoxiong Lv]

Move the 11/29 command from enable() to init() function

As mentioned in the patch:
https://lore.kernel.org/all/20240624141926.5250-2-lvzhaoxiong@huaqin.corp-partner.google.com/

Our DSI host has different modes in prepare() and enable()
functions. prepare() is in LP mode and enable() is in HS mode.
Since the 11/29 command must also be sent in LP mode,
so we also move 11/29 command to the init() function.

After moving the 11/29 command to the init() function,
we no longer need additional delay judgment, so we delete
variables "exit_sleep_to_display_on_delay_ms" and
"display_on_delay_ms".
