Series ext4l: Clean up ext4_uboot.h by moving definitions to standard headers |

Remove the iomap type constants and struct definitions that are
wrapped in a LINUX_IOMAP_H header guard. Since linux/iomap.h is already
included at the top of ext4_uboot.h, this block was dead code that
could never be compiled.

The definitions also had different values from linux/iomap.h (e.g.
IOMAP_MAPPED was 0 vs 2), which could have caused subtle bugs if the
guard was ever removed.
