kernel: add support for tw686x frame grabbers
Adds support for Intersil/Techwell tw686x frame grabbers.
By default, this module uses MEMCPY to transfer data.
Let's switch to "Contiguous DMA" which is the fastest
performing method available.
[ 10.074349] tw6869: PCI 0000:07:00.0, IRQ 33, MMIO 0x1200000 (contig mode)
[ 10.081381] tw686x 0000:07:00.0: enabling device (0140 -> 0142)
