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.

The 4.14 kernel configuration defaulted to a v4/v5 multiplatform while
4.9 was using a v6/v7 default configuration. Resync 4.14 against 4.9 so
they are nearly identical.

Enable CONFIG_VFP again which was disabled during the 4.9 -> 4.14 bump.
Boot tested both 32 and 64 bit subtargets using initramfs images with the
qemu-system-arm and qemu-system-aarch64 emulators.

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.

Remove CONFIG_SCHED_HRTICK from target configs, as it was added to the
generic config in b47fd7656336162360ebf66147326763ddae3f8d.

The kernel configs for all targets should have the version in the
filename, for clearness and consistency across all targets.
It is also expected by the update_kernel.sh script.

It was originally only enabled for the "32" subtarget along with the
"usb" feature which is now also shared by the "64" target
This should fix the phase1 build of armvirt/64

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")
