linux-%: Tweak kernel configuration for KVM demo guests
Rework the kernel configuration fragment application to prune out a bunch of the configuration for physical hardware for the virtio-aarch64 kernel. As well, add a virtio guest kernel specific fragment to enable a PCI CAN device driver that works with QEMU's emulation. That will provide a fallback until something can be worked out with respect to virtio-can. Bug-AGL: SPEC-4618 Change-Id: Ibb674d09c115ab5bbe454b665350a658c759e5f5 Signed-off-by: Scott Murray <scott.murray@konsulko.com>
