Migrate duplicated enable_vmx() method from multiple CPUs to common folder. Add common virtualization option for CPUs which support it. Note that this changes the default to enable virtualization on CPUs that support it.

help
|
|
Although the Intel manual says you must set the lock bit in addition
|
|
to the VMX bit in order for VMX to work, this isn't strictly true, so
|
|
we have the option to leave it unlocked and allow the OS (e.g. Linux)
|
|
to manage things itself. This is beneficial for testing purposes as
|
|
there is no need to reflash the firmware just to toggle the lock bit.
|
|
However, leaving the lock bit unset will break Windows' detection of
|
|
VMX support and built-in virtualization features like Hyper-V.
