ARM: PL08x: remove unnecessary includes

We don't need to include linux/pci.h as we aren't a PCI driver.  We
aren't doing any processor specific functions, so asm/processor.h is
not required.  asm/cacheflush.h shouldn't be used, we have the DMA API
for this.  DMA interfaces aren't required as we're only implementing
the dmaengine API and not a platform-private DMA API.
