Revert "lpc32xx: cpu: add support for soft reset"
This reverts commit 576007aec9a4a5f4f3dd1f690fb26a8c05ceb75f.
The parameter passed to reset_cpu() no longer holds a meaning as all
call-sites now pass the value 0. Thus, branching on it is essentially
dead code and will just confuse future readers.
Revert soft-reset support and just always perform a hard-reset for now.
This is a preparation for removal of the reset_cpu() parameter across
the entire tree in a later patch.
