arm64: dts: qcom: kaanapali-mtp: Enable display DSI devices

Enable MDSS/DPU/DSI0 and add Novatek NT37801 panel on Kaanapali MTP
board.

NT37801 Spec V1.0 chapter "5.7.1 Power On Sequence" states VDDI ranges
1.65V~1.95V, but ldo12 ranges 1.2V~1.8V, so change ldo12 range to
1.65V~1.8V.

pmh0110_d_e0_gpios and pmh0110_f_e0_gpios are configured for
level shifters. Kaanapali need configure these pinctrl for panel
function.
