It's a bit silly that we don't have any structure definition for
MPIDR. If you feel you have the time, please submit a patch to
ArmPkg/Include/Guid/ArmMpCoreInfo.h, adding one. Or maybe two - one
for the _UP variant and one for the _MP variant. If you don't have the
time, just a note to the universe that we should do this.
