In order to meet the timing, remove the delay between "backlight off"
and "display off", and reduce the delay between "display_off" and
"enter_sleep"

Removing variables: display_off_to_enter_sleep_delay_ms

Separate commit, separate _justification_. Why, not what.

hi Dmitry

As in another patch reply, in order to solve a black screen problem,
the delay is reduced.

It should be described in the commit message(s). You have removed one
delay and added another one. Is that a single fix or two separate fixes?

We only modify one of the drivers (starry), and the other driver
(boe_th101mb31ig002) is just to keep the original value.
