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. Signed-off-by: Pierre Gondois <Pierre.Gondois@arm.com> Reviewed-by: Sami Mujawar <sami.mujawar@arm.com>
