Split generic CCM handling out of ipaccess_bts_read_cb()
The generic functionality of responding to IPA CCM messages doesn't need
to be intertwined with our e1input abstraction. We split this out
as new exported function ipaccess_bts_handle_ccm() and modify
ipaccess_bts_read_cb() to make use of that function.
