arm: mach-k3: j721e_init: improve DSS order ID selection

Instead of always using order ID 9 for DSS, spread the order IDs to
prevent the transactions being handled serially.

RT transactions should have order ID >= 8, and the maximum order ID is
15. This patch uses a simple scheme where each channel is assigned an
order ID counting down from 15.

The result is that VID and VIDL pipes get a channel ID between 0x8 and
0xf, and WB gets channel ID 6 and 7.
