mb/google/bluey: Initialize display before low-power boot check

Browse source 
Currently, display_startup() is called near the end of mainboard_init.
If the system enters a low-power boot mode (such as low-battery or
off-mode charging), the function returns early, leaving the display
uninitialized.

Move display_startup() before the is_low_power_boot() check. This
ensures the display is ready to show user notifications, such as
battery status or charging icons, even when the rest of the
mainboard initialization is skipped.

TEST=Build and boot Google/Quartz.
