arm64: dts: rockchip: configure hdmirx in Rock 5 ITX
The Radxa Rock 5 ITX board exposes an HDMI input exactly the same way as
the Rock 5B, but this was not reflected in its DTS.
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.
