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.

Enable the harden branch predictor for arm64 as it is recommend.

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.
