The queued spinlock implementation requires the forward progress
guarantee of cmpxchg()/xchg() atomic operations: CAS with Zabha or
LR/SC with Ziccrse provide such guarantee.
Select this if and only if Zabha or Ziccrse is available on your
platform, RISCV_QUEUED_SPINLOCKS must not be selected for platforms
without one of those extensions.
If unsure, select RISCV_COMBO_SPINLOCKS, which will use qspinlocks
when supported and otherwise ticket spinlocks.
