misc: rtsx: Remove usage of the deprecated "pci-dma-compat.h" API
In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.
Some reasons why this API should be removed have been given by Julia
Lawall in [2].
Finally, Arnd Bergmann reminded that the documentation was updated 11 years
ago to only describe the modern linux/dma-mapping.h interfaces and mark the
old bus-specific ones as no longer recommended, see commit 216bf58f4092
("Documentation: convert PCI-DMA-mapping.txt to use the generic DMA API").
A coccinelle script has been used to perform the needed transformation
Only relevant parts are given below.
