Pass errp to load_image_targphys() calls in ppc machine initialization
to capture detailed error information when loading firmware, kernel,
and initrd images.

Use error_reportf_err() instead of error_report() to print the
underlying error details along with context about which image failed
to load.

We can get here with *errp == NULL if load_elf did not fail but tried to load a too large image. Is that a problem? It's the same in prep.c. Mac machines also try different formats but those only check for size < 0 so maybe not a problem there.
