include: sbi: Allow direct initialization via SPIN_LOCK_INIT()
The current implementation of SPIN_LOCK_INIT() provides the spinlock
to be initialized as reference. This does not allow a direct
initialization of the spinlock object at the creation site.
Let's pass the spinlock directly instead (like Linux does as well)
and adjust all users of the macro (in fact there is only one user).
