meta-agl-bsp, templates: Add virtio-aarch64 machine
This machine is intended to run in ARMv8 virtualized environment that provides VirtIO devices. AGL machine configuration files are based on qemuarm64 machine from meta-agl branch master commit e1da0efcd2eece82b0326798cfeaeb8dd48797fc. Yocto machine configuration files are based on qemuarm64 machine from Poky branch dunfell commit 4e931b1d05018923dc145cd97f6f965f5cb6e1a5. Yocto Linux Kernel is used as recommended in [1]. Its metadata for the created machine are based on qemuarm64-standard.scc from yocto-kernel-cache branch yocto-5.4 commit 4aeda12f7f7eb84613ae1fe6e22cd9cd9790c20b. The rationale behind creating new machine is a wish to have a machine that could run on other hypervisor/virtual machine monitor that implements VirtIO, not necessary QEMU. For now, virtio-aarch64 machine runs under QEMU and OpenSynergy COQOS Hypervisor. virtio-aarch64 machine includes following changes comparing to qemuarm64: * use virtio-gpu instead of VGA display (to be upstreamed to work in conjunction with runqemu gl, sdl, etc. options) * use virtio-bus instead of PCI bus QEMU devices * remove unneeded configurations Changes are moved here from meta-agl-devel.
