ieee802154: cfg802154: make wpan_phy_class constant

Browse Source 
Since commit 43a7206b09 ("driver core: class: make class_register() take
a const *"), the driver core allows for struct class to be in read-only
memory, so move the wpan_phy_class structure to be declared at build time
placing it into read-only memory, instead of having to be dynamically
allocated at boot time.
