[U-Boot-Users] [PATCH v3] fdt: add crypto node handling for MPC8{3, 5}xxE processors

crypto node if not on an E-processor. If on 8360 or 834x family,
check rev and up-rev crypto node (to SEC rev. 2.4 property values)
if on an 'EA' processor, e.g. MPC8349EA.

fixed v2's off-by-one error when accumulating compatible entry offsets
that deleted the necessary '\0' sprintf adds between strings.
