 v1 -> v2:
 * Reworded subject
 * Added memory@0 node for Bubblegum-96 (Mark)
 * Filled in reserved-memory sub-node for Bubblegum-96 (Mark)
 * Added arm-pmu interrupt-affinity property (Mark)
 * Changed second GIC reg size 0x1000 -> 0x2000 for Bubblegum-96 (Mark)
 * Updated ARCH_OWL to ARCH_ACTIONS (Arnd)
 * Renamed s900-bubblegum96.dts to s900-bubblegum-96.dts
 * Adopted "actions" vendor prefix
 * Dropped irq.h include
