ramips: restore AWM002-EVB profile in asiarf.mk

In a recent revision (r41177) John Crispin removed the profile for the
AsiaRF AWM002 eval board while adding another AsiaRF board.  This
patch restores AWM002 and also corrects a misspelling and an
apparently errant reference to an Allnet ALL0239-3G device.
