Hi,

We got an Errata # from Rockchip for the GIC600 integration issue in
RK3588, so here is another try adding upstream ITS support for that
platform. I noticed
https://lore.kernel.org/lkml/DU0PR04MB9417388F9BDD73080294FA8E88889@DU0PR04MB9417.eurprd04.prod.outlook.com/
so I kept the flag name itself generic.

P.S.: I'm taking over from Lucas Tanure, who no longer works for
Collabora.

List of previous attempts / changelog:
 * PATCHv1
  - https://lore.kernel.org/lkml/20230227151847.207922-1-lucas.tanure@collabora.com/
  - uses of_dma_is_coherent() instead of providing errata info from kernel
 * RFCv1
  - https://lore.kernel.org/lkml/20230310080518.78054-1-lucas.tanure@collabora.com/
  - uses 0x0201743b IIDR for quirk detection and misses errata #

Greetings,

-- Sebastian
