The bl2_early_platform_setup() and bl2_platform_setup() were redefined for Juno AArch32 eventhough CSS platform layer had same definition for them. The CSS definitions definitions were previously restricted to EL3_PAYLOAD_BASE builds and this is now modified to include the Juno AArch32 builds as well thus allowing us to remove the duplicate definitions in Juno platform layer.
