fix(bl2): make BL2 SRAM footprint flexible

On FVP's the default SRAM size is severly restrictive. However, more
recent models support larger SRAM configurations (> 256 Kb). We
introduced the flag FVP_TRUSTED_SRAM_SIZE to allow for TF to handle
different configurations.

BL31 automatically benefits from this optimisation since it starts from
the bottom of shared memory, and runs up to the end of SRAM. Increase
the size of all BL2 builds in proportion to FVP_TRUSTED_SRAM_SIZE so
that BL2 covers around a third of SRAM.
