DynamicTables: Fix DT PCI interrupt flags parsing
Device Tree PCI interrupt flags use the convention described at
linux/Documentation/devicetree/bindings/interrupt-controller/arm,gic.yaml
The 3rd cell is the flags, encoded as follows:
bits[3:0] trigger type and level flags.
1 = low-to-high edge triggered
2 = high-to-low edge triggered (invalid for SPIs)
4 = active high level-sensitive
8 = active low level-sensitive (invalid for SPIs).
Fix the incorrect code.
