fdt: add crypto node handling for MPC8{3, 5}xxE processors
Delete the 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. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
