Implement ACPI APEI ERST feature

APEI are ACPI4.0 new features. It consists of ERST, BERT, HEST, and
EINJ.  ERST is used to save fault error log to a platform persistent
storage, so that when reboot os can retrieve the error log and handle
it.

This patch is used to implement ERST feature to Xen.  It consists of
3-level hierarchy: operation level, action level, and instru= ction
level.  Instruction do basic io; Action done by sequential
instructions parsed from ACPI ERST table; Operation done by
sequential actions defined by ACPI spec, providing erst_write/
erst_read/ erst_clear interfaces to MCE/ NMI/ PCIe error handling
mechanism, etc.
