media: tw68: switch from 'pci_' to 'dma_' API
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'tw68_risc_buffer()' (tw68-risc.c) GFP_KERNEL
can be used because this function is only called from a vb2_ops buf_prepare
function.
The call chain is:
tw68_video_qops.buf_prepare (tw68-video.c)
--> tw68_buf_prepare (tw68-video.c)
--> tw68_risc_buffer
