Juno AArch32: Remove duplicate definition of bl2 platform API

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.
