Add virtio-aarch64 platform description via scc file.
Metadata is based on qemuarm64-standard.scc from
yocto-kernel-cache branch yocto-5.15 commit
947149960e1426ace478e4b52c28a28ef8d6e74b with a lot of unended
configurations removed.
Comparing to initial version [1] many TODOs have been removed since
changes landed upstream (yocto-kernel-cache).
Note, that BSP description root file virtio-aarch64-standard.scc has to
be kept local withing a recipe. This is needed to add this scc file
explicitly to SRC_URI to have AGL VIRTIO patches applied during kernel
recipe build.
As explained in [2, 3], Yocto kernel metadata is commonly used for two
purposes:
1. To construct Yocto kernel git by committing patches listed in scc
files.
2. To configure Yocto kernel during Yocto build.
When scc file is not explicitly added to SRC_URI, then patch commands
will be ignored during Yocto build because it is assumed that patches
are already pre-applied during Yocto kernel git tree construction.
But, there is not AGL Linux kernel tree, only a repository for AGL
kernel metadata (this one). So, patches from this metadata repository
have to be applied during kernel recipe build.
