[edk2-devel] [PATCH] MdePkg/Acpi64: Update Error Severity type for Generic Error Status Block

[Wu, Hao A]

Starting from ACPI Specification Version 5.1 Errata B, the term
'Correctable' is no longer being used as an error severity of the
reported error in Chapter 18 APEI.

This commit adds a new macro to reflect this and also keeps the origin
definition (but add comments to make it deprecated) for compatibility
consideration.

Please also note that this commit only updates Acpi64.h and
does NOT update below headers:
Acpi51.h
Acpi60.h
Acpi61.h
Acpi62.h
Acpi63.h
