Add the necessary DT changes to enable HDMI0 on Radxa ROCK 5A.

Since the initial support for the RK3588 HDMI TX Controller [1] has been
merged as of next-20241018, let's enable the HDMI0 output port for the
following boards: Radxa ROCK 5A & 5B, Rockchip RK3588 EVB1 V10, Xunlong
Orange Pi 5+.

Thanks,
Cristian

Changes in v3:
- Used the proper (i.e. micro) HDMI connector type for ROCK 5A (Jonas)
- Rebased series onto next-20241022 and dropped patches already merged
  by Heiko
- Link to v2: https://lore.kernel.org/r/20241019-rk3588-hdmi0-dt-v2-0-466cd80e8ff9@collabora.com

Changes in v2:
- Updated descriptions for rock-5a & rock-5b patches to include Radxa,
  per Naoki's review; also collected his Tested-by on the latter
- Included Naoki's HPD pin related fix in rock-5a patch and dropped the
  UNTESTED prefix from the subject
- Link to v1: https://lore.kernel.org/r/20241019-rk3588-hdmi0-dt-v1-0-bd8f299feacd@collabora.com
