[PATCHv3 bluetooth-next 3/4] ieee802154: move mac pib defaults

[Alexander Aring <alex.aring@gmail.com>]

This patch moves the mac pib defaults setting out of SoftMAC layer. This
will prepare for possible HardMAC drivers that these values are 802.15.4
defaults while netdev registration. Currently the SoftMAC layer is the wrong
place to do the settings of pib defaults.
