  From: Simon Glass <sjg@chromium.org>

The Linux kernel isofs source files include kernel-specific headers
(<linux/gfp.h>, <linux/slab.h>, <linux/cdrom.h>, etc.) that are not
available in U-Boot. Replace these with the single internal isofs.h
header, which pulls in the U-Boot compatibility layer.

The only modification to each file is replacing the Linux includes
with #include "isofs.h" and adding a "Ported to U-Boot" comment.
