arm64: dts: qcom: sm8450: Use GIC-ITS for PCIe0 and PCIe1
Both PCIe0 and PCIe1 controllers are capable of signalling the MSIs
received from endpoint devices to the CPU using GIC-ITS MSI controller.
Add support for it.
Currently, BDF (0:0.0) and BDF (1:0.0) are enabled and with the
msi-map-mask of 0xff00, all the 32 devices under these two busses can
share the same Device ID.
The GIC-ITS MSI implementation provides an advantage over internal MSI
implementation using Locality-specific Peripheral Interrupts (LPI) that
would allow MSIs to be targeted for each CPU core.
It should be noted that the MSIs for BDF (1:0.0) only works with Device
ID of 0x5980 and 0x5a00. Hence, the IDs are swapped.
