drm/amd/display: Increase array size of dummy_boolean

Browse Source 
[WHY]
dml2_core_shared_mode_support and dml_core_mode_support access the third
element of dummy_boolean, i.e. hw_debug5 = &s->dummy_boolean[2], when
dummy_boolean has size of 2. Any assignment to hw_debug5 causes an
OVERRUN.

[HOW]
Increase dummy_boolean's array size to 3.

This fixes 2 OVERRUN issues reported by Coverity.
