sb/intel/lynxpoint: Add Kconfig option to hide Intel ME
On lynxpoint devices, coreboot currently disables and hides the ME PCI
interface by default, without any way to opt out of this behavior.
Add a Kconfig option to allow for leaving the ME PCI interface
enabled, but set the default to disabled as to leave the current
behavior unchanged.
