arm64: dts: imx93-9x9-qsb: Add tianma,tm050rdh03 panel

Support tianma,tm050rdh03 DPI panel on i.MX93 9x9 QSB.

Move the common parts from imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtso into
imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtsi for reuse by the tm050rdh03
overlay file.

The panel connects with the QSB board through an adapter board[1]
designed by NXP.
