Attestation token larger than 4 KB is not supported in RMM-EL3 interface #24

Although the RMM allows CCA attestation token sizes of larger than 4KB, there is a limitation on the size of the Platform attestation token part. On the RMM-EL3 interface, there is only a shared buffer of 4KB that is currently shared on the FVP. This needs to be enhanced so that larger platform token sizes can be tested.
