x86: Select advanced Intel code only if allowed
At present most of the Intel-specific code is built on all devices, even
those which don't have software support for the features provided there.
This means that any board can enable CONFIG_INTEL_ACPIGEN even if it does
not have the required features.
Add a new INTEL_SOC option to control this access. This must be selected
by SoCs that can support the required features.
