[PATCH 2/2] cdc_ncm: add support FLAG_NOARP for Infineon modem platform

[Wei Shuai <cpuwolf-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Infineon(now Intel) HSPA Modem platform NCM cannot support ARP.
we can define a new common structure wwan_noarp_info.
Then more similiar NO ARP devices can be handled easily
