feat(fvp): allow configurable FVP Trusted SRAM size

In some build configurations TF-A can exceed the existing 256KB SRAM,
triggering a build failure. More recent versions of the base FVP allow
you to configure a larger Trusted SRAM of 512KB.

This change introduces the `FVP_TRUSTED_SRAM_SIZE` build option, which
allows you to explicitly specify how much of the Trusted SRAM to
utilise, e.g.:

    FVP_TRUSTED_SRAM_SIZE=384

This allows previously-failing configurations to build successfully by
utilising more than the originally-allocated 256KB of the Trusted SRAM
while maintaining compatibility with older configurations/models that
only require/have 256KB.
