fvp: increase sram size

Few configurations are on size edge and any simple additions
can cause them to cross the 256KB limit.

Some of the configurations in this patch fail to compile on simple
additions to Bl31 example smccc-1.5 vendor specific el3.

So increase the sram limit to 384KB for these builds.
