Change the rk3588-rock-5-itx to configure and enable the hdmi_receiver and hdmi_receiver_cma nodes. The hot-plug detection (HPD) pin keeps the hdmirx_det name rather than the hdmirx_hpd name used in other boards since that is what matches the official schematics (HDMIIRX_DET_L). The configurations were confirmed to be identical on the downstream Radxa kernel, and this has been tested to work on a Rock 5 ITX board running kernel 6.19.3.
