rk3576 is using dwc controller, with msi interrupt directly to gic instead

- no its support is required and the 'msi-map' is not need anymore,
- a new 'msi' interrupt is needed.

Commit msg said new interrupt, but this basically replaces existing DMA0
interrupt. Maybe that's the problem with this common binding and you
just miss constraining in each device binding. If so: fix also them.
rk3588 has 9 interrupt, and the 6th-9th is dma0-3;
rk3568 only has 5 interrupts, no dma0-3;
rk3576 add one more "msi" interrupt which is the 6th interrupt;
The upcomming rk3562 is the same as rk3576.
I'm sorry I'm not so good at this yaml grammar, how should I take care
of this case?
Thanks,

Also: your interrupts property does not match this anymore.
Best regards,
Krzysztof
