cpu/x86: Make 1GB paging the default
This patch flips the polarity of CONFIG_USE_1G_PAGES_TLB into CONFIG_NEED_SMALL_2MB_PAGE_TABLES which is off by default, meaning CPUs added in the future will automatically build the smaller 1GB pages. We can expect support for this feature to be available on all future CPU generations (with the possible exception of embedded edge cases), so this default setting should make mistakes less likely and keep maintenance effort lower. (Besides, enabling the support where it doesn't work fails fast, whereas keeping it disabled where it could work is an inefficiency that can easily go overlooked for a long time.) While this is technically a CPU feature, not a northbridge feature, we support a lot more individual CPUs than northbridges in the pre-SoC era, and they tend to be closely coupled anyway. So select the option at the northbridge level for older CPUs to keep things simpler.
