Subject: [PATCH v3 2/7] dt-bindings: PCI: dw: rockchip: Add rk3576 support

rk3576 is using dwc controller, with msi interrupt directly to gic instead
of to gic its, so
- no its suport is required and the 'msi-map' is not need anymore,
- a new 'msi' interrupt is needed.

Signed-off-by: Kever Yang <kever.yang@...k-chips.com>

Changes in v3:
- Fix dtb check broken on rk3588
- Update commit message

Changes in v2:
- remove required 'msi-map'
- add interrupt name 'msi'
