usb: misc: Add snapshot of MDM data bridge and transport drivers 



Add snapshot of MDM data bridge host and gadget transport drivers
from msm-3.10 commit 7615003cb4c9 ("dsp: asm: Add check for
num_channels before calling q6asm_map_channels").
On top of this, make following changes:
 - Rename u_data_usb.c to f_mdm_data.c to use it as function
   driver (more changes will be added in subsequent patch)
 - Fix copyright info.
 - Fix checkpatch warnings and errors (requires some cleanup of
   ctrl path logic, more cleanup will of the same will be done in
   subsequent patch).
