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
Removing the Kconfig variable STACK_SIZE to use the default results
in the following numbers of stack usage.
$ grep stack coreboot_with_patch.log
CPU1: stack_base 00287000, stack_end 00287ff8
CPU1: stack: 00287000 - 00288000, lowest used address 00287da8, stack used: 600 bytes
CPU0: stack: 00288000 - 00289000, lowest used address 0028875c, stack used: 2212 bytes
