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:

We use 5.4 on all targets by default, and 4.19 has never been released
in a stable version. There is no reason to keep it.

It is deactivated everywhere, just set this in the generic config.

This target was switched to kernel 4.19 more than 6 months ago in commit
f342ffd300 ("treewide: kernel: bump some targets to 4.19") and now
with kernel 5.4 support being added it gets harder to support kernel
4.14 in addition to kernel 4.19 and 5.4.

It's just copy of 4.14 and will be refreshed in the upcoming commit,
renamed config-default to config-4.14 as well.

This removes support for executing old 32 bit applications on 64 bit ARM
and MIPS kernels.
On OpenWrt we normally compile all the user space applications on our
own and do not support third party binary only modules especial not 32
bit applications on 64 bit CPUs.
This reduces the attack surface on such systems and should also save
some memory.

This activates "Emulate Privileged Access Never using TTBR0_EL1
switching" on ARM64.
This should prevent the kernel from reading code from user space in
kernel context.

In 4.14.57, a new symbol for Spectre v4 mitigation was introduced for
ARM64. Add this symbol to all ARM64 targets using kernel 4.14.
This mitigates CVE-2018-3639 on ARM64.

While bumping 4.14, the kernel build failed due to missing CONFIG_KASAN
symbol. Move it to generic config instead of defining it for all arm64
and x86/64 targets.
It was only added in 4.0, so not needed in config-3.18.

We will be prompted with this config symbol when performance monitoring is
enabled in the kernel.

Original armvirt target is now subtarget 32. Other than that the built
result should remain the same as before
Besides old features already available with arm64, the new armvirt/64
subtarget will also have those features originally enabled for
armvirt/32 with commit 44ecfc2 ("armvirt: new target")
