On socfpga_socrates, 1304 bytes are currently used (and this increases by ~200 bytes only for the sdram/reset fixes in socfpga-next). To prevent wasting precious SRAM space, let's reduce the initial heap used for SPL to 2 KiB. This is still some hundred bytes more than currently used. Also, the gen5 SPL enables stack and heap in DDR memory pretty early. Only the initial uclass/dm parsing, serial console and DDR initialization is done in the initial heap, so these 2 KiB should be enough for all boards.
