Subject: [PATCH 3/6] arm64: dts: ls1043a: update MSI and PCIe node

1. Change compatible to "fsl,ls-scfg-msi"
2. Move three MSI dts node into the parent node "msi-controller".
So a PCIe device can request the MSI from the three MSI controllers.
3. The rev1.1 of LS1043a moves PCIe INTB/C/D interrupts to MSI controller.
