ENCLS is an umbrella instruction for a variety of cpl0 SGX functions.
The ENCLS function that is executed is specified in EAX, with each
function potentially having more leaf-specific operands beyond EAX.
ENCLS introduces its own (positive value) error codes that (some)
leafs use to return failure
Define the data structures used by various ENCLS functions needed for
Linux to support all SGX1 and SGX2 ENCLS leaf functions. This is not
an exhaustive representation of all SGX data structures as several are
only consumed by ENCLU (userspace), e.g. REPORT and KEYREQUEST, while
others are only co
