drivers: ieee802154: fix nrf5 initialization with external irq source

Browse source 
MPSL is a library that provides external radio IRQ source for the
802.15.4 driver. If this library is in use, the driver shall not
configure the radio IRQ.

help
The driver may manage radio IRQs by itself, or use an external
radio IRQ provider. When radio IRQs are managed by an external
provider, the driver shall not configure radio IRQs.
Enable this option when external radio IRQ provider is enabled in
the system. One example of external radio IRQ provider could be
a radio arbiter used in dynamic multiprotocol applications.
