mpc83xx: remaining 8360 libfdt fixes
PCI clocks and QE frequencies weren't being updated, and the core clock was being updated incorrectly. This patch also adds a /memory node if it doesn't already exist prior to update. plus some cosmetic trimming to single line comments. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
