Hi.

I am proposing a Device Tree Blob for the Firefly ITX-3588J board.
This is another Mini-ITX form-factor board for the Rockchip RK3588
SoC, along with the ROCK 5 ITX. This is so far a draft copy meant
for review and suggestions as there are still some issues.

It's also important to note this was originally being worked on with
a specific aim to include it in a UEFI firmware package; as a result
it has a few differences (like a pre-built "chosen" bootargs and
disabling the eMMC) that may not make sense in a final kernel tree;
I'm posting this for feedback and not as a final proposal as those
are relatively easy to reverse and so don't affect the tree
substantially.

Issues outstanding:
 * Suspend does not work.
 * The USB-C port does not work.
 * Unsure how to get control over the main LED; the commented part
   seems to cause a failure.
 * Audio output on the back green port does not seem to work; but I
   found this may be due to slight inadequacy of the still-new ES8323
   driver - can suggest a patch for that too separately.
 * Not sure if there are other board features that could be enabled
   for the present kernel.

Thanks,
Shimrra
