Paul Menzel d654f42e27 AMD: Reduce stack size from 64 KB to the default of 4 KB
Apply the following commit to all AMD boards.

    commit 935850e082

        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.

    $ git grep STACK_SIZE src/vendorcode/amd

The following command was used to create the patch.

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