Shikra boards currently boot Linux under a hypervisor, where the remote processor firmware IOMMU streams are managed by the hypervisor. When booting Linux directly at EL2 without the hypervisor, the IOMMU is instead managed by the consumer of this DeviceTree, so the firmware streams for each remote processor need to be described explicitly. Add an EL2-specific DT overlay and apply it to all Shikra EVK variants devices to produce an -el2.dtb alongside the "normal" dtb. Signed-off-by: Komal Bajaj <komal.bajaj@oss.qualcomm.com>
