layerscape: update README
Tis patch is to fix up some descriptions in README. Per-device rootfs had been supported, and a known issue had been found. These also should be updated accordingly. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>

+* u-boot may fail to read MAC addresses from EEPROM on some boards and there
+ won't be MAC addresses set in environment. This may cause kernel fails to
