msm: ipa: CV2X header file changes

For QMI dpm port to open, control manager needs
to know about usb/mhi ep details corresponding to
RMNET and RMNET_CV2X tethering.
IPA driver has all endpoint info at one place.
 - provide IOCTL interface to get ep_pair info.
 - Add support for new dtsi entry specifying auto config.
 - Add support in ipa-usb driver for rmnet_cv2x.
