soc/intel/apollolake: Add CFR objects for existing options

Browse source 
Add a header with CFR objects for existing configuration options,
so that supported boards can make use of them without duplication.

CFR options are added for the following options:
- legacy_8254_timer
- s0ix_enable
- vtd

TEST=build/boot google/reef with CFR support
