soc/intel/braswell: add vmx support via CPU_INTEL_COMMON
Braswell allready supported vmx, but offered no mechanism to unset it, nor
to set the lock bit required for Windows to recognize virtualization.
Enable this functionality by adding CPU_INTEL_COMMON config.
Test: build/boot Windows 10 on Braswell ChromeOS device, verify Windows shows
virtualization as enabled.
