staging: rtl8192e: rtl_core: Remove pci-dma-compat wrapper APIs.
The legacy API wrappers in include/linux/pci-dma-compat.h
should go away as it creates unnecessary midlayering
for include/linux/dma-mapping.h APIs, instead use dma-mapping.h
APIs directly.
The patch has been generated with the coccinelle script below
and compile-tested.
