[media] drivers: media: usb: b2c2: use usb_*_coherent() instead of pci_*_consistent...

Some architectures do not support PCI, but still support USB, so need
let our usb driver try to use usb_* instead of pci_* to support these
architectures, or can not pass compiling.
The related error (with allmodconfig for arc):
    CC [M]  drivers/media/usb/b2c2/flexcop-usb.o
  drivers/media/usb/b2c2/flexcop-usb.c: In function ‘flexcop_usb_transfer_exit’:

  drivers/media/usb/b2c2/flexcop-usb.c:410: error: implicit declaration of function ‘pci_alloc_consistent’
