At the request of Logic PD, this patch sets the display parameters to
match that of Logic PD's display type 28 since type 15 is discontinued.
V2: A previous patch attempted to eliminate an warning indicating no
power supply for the LCD. This undoes some of those patches to make
the Type 28 display work correctly.
V1: First attempt to enable Type 28 display from Logic PD.
