To avoid failure of dt_binding_check perform a slight refactoring
of the examples: the main block is kept, but that required fixing
the address and size cells, plus the inclusion of missing dt-bindings
headers, required to parse some of the values assigned to various
properties.

Fixes: 4ed545e7 ("dt-bindings: display: mediatek: disp: split each block to individual yaml")
