Arthur Heymans e7266e8393 cpu/x86/entry16.S: Make Intel CBnT TOCTOU safe 
Intel CBnT (and Boot Guard) makes the chain of trust TOCTOU safe by
setting up NEM (non eviction mode) in the ACM. The CBnT IBB (Initial
BootBlock) therefore should not disable caching.

Sidenote: the MSR macros are taken from the slimbootloader project.

TESTED: ocp/Deltalake boot with and without CBnT and also a broken
CBnT setup.
