- new hyperv.mak in default configs
- Move changes from x86_64-softmmu.mak to i386-softmmu.mak
- Added CONFIG_VIRTIO_MMIO to aarch64-softmmu.mak
- Removed config_vga_isa.c changes as no longer needed
- Removed new devices

Merged patches (qemu 3.1.0):
- d51e082 Re-enable CONFIG_HYPERV_TESTDEV
- 4b889f3 Declare cirrus-vga as deprecated
- b579d32 Do not build bluetooth support
