Enable SMMUv3 AEM for FVP running spm tests

SPM(reference implementation of S-EL2 firmware) has SMMUv3 driver
enabled to help with stage-2 translation and virtualization of
upstream peripheral devices. Hence, enable the SMMUv3 IP in FVP
by configuring the appropriate parameters of the SMMUv3 AEM in
various spm run fragments.

Also, remove few SMMU AEM related parameters which pass default values
to related parameters. This makes the FVP AEM model command line
simpler.
