wda: extended wda set format message to enable QMUX

Added the following configurable values:
- upload datagram protocol
- download datagram protocol
- download datagram max size
- download max datagrams
- endpoint type
- endpoint interface number

According to last GobiNet from CodeAura project, it is necessary to set
the following values to enable multiple data connection through one
controller device:

- upload datagram protocol   = QMAP
- download datagram protocol = QMAP
- download datagram max size = 32 (it seems working even without setting it)
- download max datagrams     = 32768 (it seems working even without setting it)
- endpoint type              = HSUSB (it seems working even without setting it)
- endpoint interface number  = this depends on the modem, but it seems working
  even without setting it
