[PATCH] atm: atmtcp: Constify atmtcp_v_dev_ops

[Rikard Falkeborn]

The only usage of atmtcp_v_dev_ops is to pass its address to
atm_dev_register() which takes a pointer to const, and comparing its
address to another address, which does not modify it. Make it const to
allow the compiler to put it in read-only memory.
