arm64: configs: Add virtconfig
Provide a slimline configuration intended to be booted on virtual
machines, with the goal of providing a light configuration which will
boot on and enable features available in mach-virt. This is defined in
terms of the standard defconfig, with an additional virt.config fragment
which disables options unneeded in a virtual configuration.
As a first step we just disable all the ARCH_ configuration options,
disabling the build of all the SoC specific drivers. This results in a
kernel that builds about 25% faster in my testing, if this approach
works for people we can add further options.
