[Guam NA] Fix propagation error in dsi_display.c

Fix conditions placement error in dsi_display_disable() and
dsi_display_unprepare(), which were swapped probably due to a mistake
during propagation.

Now, the display turns on correctly and the moto extended dsi features
can be used.

The MMI_STOPSHIP will be removed from bengal-guamna-display.dtsi in a
follow-up commit.
