Yes it is the correct behavior, it was wrong before. If the
HFC_CHIP_2MBITRAW flag is set, only hc->chan[0] should be used.
This did not make trouble, because you normally do not use any
D-channnel in 2 MBit mode, calling the D-Channel specific functions
still makes sense for the L1 state machine, when using this
mode to emulate a E1 Layer1 tester, which was the main reson to
implement this mode.
