ARM: dts: keystone-k2g: Add PRU system events for virtio Two PRU system events "vring" and "kick" have been added to each PRU node in each of the PRU-ICSS0 and PRU-ICSS1 remote processor subsystems to enable the virtio/rpmsg communication between MPU and that PRU core. The additions are done in the common base keystone-k2g.dtsi file, and so are inherited by all 66AK2G boards. The PRU system events is the preferred approach over using the alternate IPCGR registers, as it eliminates an external MMR access from the PRU-side, and keeps the interrupt generation internal to the PRUSS. The difference from MPU would be minimal in using one versus the other. Note that the 66AK2G SoCs do not have the OMAP Mailbox IP, so there is no option of using mailboxes.
