dma-mapping: fix filename references

After commit cf65a0f6f6 ("dma-mapping: move all DMA mapping code to
kernel/dma") some of the files are referring to outdated information,
i.e. old file names of DMA mapping sources. Fix it here.

Note, the lines with "Glue code for..." have been removed completely.

===========================================
Multiple x86-64 PCI-DMA mapping implementations exist, for example:
1. <lib/dma-direct.c>: use no hardware/software IOMMU at all
1. <kernel/dma/direct.c>: use no hardware/software IOMMU at all
(e.g. because you have < 3 GB memory).
