Recent #10062 added support for the supervisor.runtime.display property, which holds a reference to a designated primary display.

For deep sleep, displays are released. For fake deep sleep, the C function board_init() is called so as to simulate the board reset sequence. However, boot.py is not re-run in the case of fake deep sleep.

A consequence of this is that supervisor.runtime.display will be cleared for fake deep sleep, and the display will not be available when fake deep sleep finishes and code.py is restarted.

This reduces the benefit of using boot.py to set up a display on projects that use deep sleep.
