Add DT for DHCOR Testbench board, which is a testbench for testing of DHCOR SoM during manufacturing. This is effectively a trimmed down version of AV96 board with CSI-2 bridge, HDMI bridge, WiFi, Audio and LEDs removed and used as GPIOs instead. Furthermore, the PMIC Buck3 is always configured from PMIC NVM to cater for both 1V8 and 3V3 SoM variant.
