Add 'mediatek,disable-single-burst' setting. This property can be
used to switch bus burst type, from single burst to INCR, which is
determined by the bus type within the IP. Some versions of the IP
are using AXI bus, thus this switch is necessary as 'single' is not
the burst type supported by the bus.
