asrock/e350m1: reduce default stack size

The stack used on the ASRock E350M1 is significantly less than
            what we currently set (64k per core). In fact, we use about half
            of the default stack size (4k) on core 0 and even less on non
            BSP cores [1]:

$ grep stack coreboot_without_patch_but_monotonic_timer.log
            CPU1: stack_base 002a0000, stack_end 002afff8
            CPU1: stack: 002a0000 - 002b0000, lowest used address 002afda8, stack used: 600 bytes
            CPU0: stack: 002b0000 - 002c0000, lowest used address 002bf75c, stack used: 2212 bytes

Please note that AGESA seems to define bigger stack sizes. But
    these seem to be too much too.

The following command was used to create the patch.

$ git grep -l STACK_SIZE src/mainboard/ | xargs sed -i '/STACK_SIZE/,+3d'
