boards: cxd56xx: Add wifi_smp configuration

Summary:
- This commit adds a wifi_smp configuration for spresense
- To avoid deadlock, gs2200m_irq_enable() and gs2200m_irq_disable()
  release global spinlock if they are not called on CPU0.

Impact:
- Only affects spresense:wifi_smp

Testing:
- Tested with ostest, renew, smp, telnetd.
- NOTE: tcpserver might be unstable
