Add SMP support in the bootrom. In particular,
pause all harts except
0
at the beginning of the bootrom,
let all harts jump to next boot stage after hart
0
finished bootrom,
park all harts except
0
at the beginning of crt0 for now (to be extended).
To facilitate this,
increase the number of scratch registers from 4 to 16 (e.g. for boot address synchronisation),
add a register containing the number of harts.
