arm64: dts: imx93: Add parallel display output nodes

Browse Source 
Add required OF nodes to support the i.MX93 parallel output (DPI) path.

On the i.MX93 a single LCDIF is connected to three bridges: DPI, LVDS
LDB and the MIPI-DSI whereas the i.MX91 support only the DPI bridge.

Map endpoint@0 as DPI bridge output since the i.MX93 TRM (Figure 485.
MEDIAMIX block diagram) doesn't mention any port-number <-> bridge
combination.

Set the MEDIA-AXI and MEDIA-APB clocks to the overdrive (OD) values
since the i.MX93 and i.MX91 use the overdrive (OD) clk settings per
default.
