Package architecture aarch64_generic [1] can be used just with three
devices. One is NanoPI R2S and then there are two development boards
from NXP. Let's change armvirt/64 to Cortex A53 (aarch64_cortex-a53)
[2]. It has wider support by multiple devices like NanoPI Neo Plus2/Core2,
ESPRESSObin, Pine64, and Raspberry Pi 2&3.

While looking at ARMvirt/32 it has set CPU_TYPE and CPU_SUBTYPE to be
arm_cortex-a15_neon-vfpv4 [3]. It has support to devices like
Linksys EA8500 v1, Linksys EA7500 v1, Netgear D7800, Netgear R7500 and so on.

Tested with:
qemu-system-aarch64 -m 1024 -smp 2 -cpu cortex-a57 -M virt -nographic \
-kernel openwrt-armvirt-64-Image-initramfs

Successfully compiled and booted.
Here goes the output:
root@OpenWrt:/# uname -a
Linux OpenWrt 5.4.82 #0 SMP Sun Dec 13 12:52:10 2020 aarch64 GNU/Linux
root@OpenWrt:/# cat /etc/openwrt_release
DISTRIB_DESCRIPTION='OpenWrt SNAPSHOT r15207-96fca0f807'

Also, change BOARDNAME to be the same as it is in armvirt/32.
