[edk2-devel] [PATCH v2 01/11] ArmPkg/ArmScmiDxe: Rename PERFORMANCE_PROTOCOL_VERSION

["PierreGondois" <pierre.gondois@arm.com>]

From: Pierre Gondois <pierre.gondois@arm.com>

Rename PERFORMANCE_PROTOCOL_VERSION to reflect the different
versions of the protocol. The macro is neither used in edk2 nor
in edk2-platforms.
