This was discovered when trying to run OpenWrt on Hetzner Cloud's
Arm-based instances.
Hetzner uses QEMU/KVM with virtio-gpu as the main display device,
together with an ACPI firmware. This was not displaying a console
previously.
This setup can be emulated by qemu using options below:
qemu-system-aarch64 \
-machine virt \
-bios QEMU_EFI.fd \
-device virtio-gpu \
-usb \
-device qemu-xhci,id=xhci \
-device usb-tablet,bus=xhci.0 \
-device usb-kbd,bus=xhci.0 \
-vnc :0

A review of the generated OpenWrt kernel .config
vs the Linux arm64 defconfig showed that this
option was not being enabled, as it is disabled
in OpenWrt's generic config.
ACPI_BUTTON is needed to report and respond to
power button events, so it should be enabled.

Now that the armvirt target supports real hardware, not just
VMs, thanks to the addition of EFI, rename it to something
more appropriate.
'armsr' (Arm SystemReady) was chosen after the name of
the Arm standards program.
The 32 and 64 bit targets have also been renamed
armv7 and armv8 respectively, to allow future profiles
where required (such as armv9).
