Enable support for Virtualization Host Extensions (VHE)

configname: CONFIG_ARM64_VHE

└─>Enable support for Virtualization Host Extensions (VHE)
In linux kernel since version 4.1 (release Date: 2015-06-21)  
Virtualization Host Extensions (VHE) allow the kernel to run
directly at EL2 (instead of EL1) on processors that support
it. This leads to better performance for KVM, as they reduce
the cost of the world switch.

Selecting this option allows the VHE feature to be detected
at runtime, and does not affect processors that do not
implement this feature.
