KVM: x86: smm: add structs for KVM's smram layout

Browse source

Add structs that will be used to define and read/write the KVM's
SMRAM layout, instead of reading/writing to raw offsets.

Also document the differences between KVM's SMRAM layout and SMRAM
layout that is used by real Intel/AMD cpus.
