[edk2-devel] [PATCH 1/2] ArmPkg: Add ARM SMC Architecture calls to ArmStdSmc.h

[Rebecca Cran]

The ARM SMC Architecture calls were missing from ArmStdSmc.h. Add
them, and remove the version numbers for the SMCCC and PSCI since
they're unused and look like they may have been for code that's no longer
present.
