target-i386: use memory API to implement SMRAM
Remove cpu_smm_register and cpu_smm_update. Instead, each CPU address space gets an extra region which is an alias of /machine/smram. This extra region is enabled or disabled as the CPU enters/exits SMM. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
