This series adds a feature to the ASPEED machine that allows the guest
to cause itself to exit. It was tested with romulus-bmc and palmetto-bmc
with a Linux kernel as the guest.

To test:

 cd linux
 $ export ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
 $ make aspeed_g4_defconfig
 $ ./scripts/config -e CONFIG_POWER_RESET_SYSCON_POWEROFF -e CONFIG_POWER_RESET
 $ make -j$(nproc)
 $ qemu-system-arm -M palmetto-bmc -nographic \
    -kernel arch/arm/boot/zImage \
    -dtb arch/arm/boot/dts/aspeed-bmc-opp-palmetto.dtb \
    -initrd ~/buildroot-arm.cpio.xz
