Add the necessary DT changes to enable the second HDMI output port on
Radxa ROCK 5B.

While at it, switch the position of &vop_mmu and @vop to maintain the
alphabetical order.

We're seeing failures in the Arm lab the IGT tests on this board in
Linus' tree which bisect to 77cea7ca1368 which is this patch.
core_getversion fails:

[...]

The board is running fine in -next so hopefully there's a fix already
there which will make it's way to Linus' tree during the merge window.
We're also seeing something broken with the HDMI audio devices, but I
didn't look into that.

I guess the root cause for the problem is, that the pull request for
the PHY subsystem [0] has not yet been merged. It contains [1]
("phy: phy-rockchip-samsung-hdptx: Don't use dt aliases to determine phy-id"),
a fix for properly handling the second RK3588 HDMI PHY instance.
