Several small improvements of the stack checking code:
- move the CPU0 stack check right before jumping to the payload
and out of hardwaremain (that file is too crowded anyways)
- fix prototype in lib.h
- print size of used stack
- use checkstack function both on CPU0 and CPU1-x
- print amount of stack used per core

Test: Boot coreboot on Link, see the following output:
...
CPU1: stack: 00156000 - 00157000, lowest used address 00156c68,
stack used: 920 bytes
CPU2: stack: 00155000 - 00156000, lowest used address 00155c68,
stack used: 920 bytes
CPU3: stack: 00154000 - 00155000, lowest used address 00154c68,
stack used: 920 bytes
...
Jumping to boot code at 1110008
CPU0: stack: 00157000 - 00158000, lowest used address 00157af8,
stack used: 1288 bytes
