Merged in merlin17/nuttx/mac802154-sock (pull request #479)

    wireless/ieee802154: Adds support for receiving MAC events via IOCTL through socket interface. Other small fixes and cleanup

    * ioctl: Cleans up MAC802154IOC values
    * wireless/ieee802154: Cleans up MAC802154IOC_NOTIFY_REGISTER logic in character driver
    * wireless/ieee802154/mac802154_netdev:  Adds support for MAC event notification via IOCTL
    * wireless/ieee802154/mac802154: Changes reset logic. No longer reset extended address.
    * wireless/ieee802154: Cleans up MAC802154IOC logic

        Moves MAC802154IOC from ieee802154_ioctl.h and renames ieee802154_ioctl.h to ieee802154_device.h since it only contains types relevant to the MAC char device now.

    * wireless/ieee802154/mac802154_device: Cleans up IOCTL logic for recent changes.
    * drivers/wireless/ieee802154/mrf24j40: Adds missing break in case statement
    * wireless/ieee802154/mac802154_netdev: Starts adding support for passing MAC events via IOCTL
    * wireless/ieee802154/mac802154: Fixes issue with receiver enable logic
    * wireless/ieee802154/mac802154: Fixes issue where extended address is cleared and not rewritten after radio reset
    * configs/clicker2-stm32/mrf24j40-mac: Enables RAMLOG and wireless driver logging
    * wireless/ieee802154/mac802154: Fixes poll logic meant to automatically choose address mode based on short address range.
