Drop "x86/cpu: Add Tremont to the cpu vulnerability whitelist" 

We don't have this CPU ID, and I don't see the point in adding it
right now.

Subject: x86/cpu: Add Tremont to the cpu vulnerability whitelist
commit cad14885a8d32c1c0d8eaa7bf5c0152a22b6080e upstream
Add the new cpu family ATOM_TREMONT_D to the cpu vunerability
whitelist. ATOM_TREMONT_D is not affected by X86_BUG_ITLB_MULTIHIT.
ATOM_TREMONT_D might have mitigations against other issues as well, but
only the ITLB multihit mitigation is confirmed at this point.
