layerscape: fix board name for SD card boot
Many Layerscape boards support both flash boot and SD card boot. And different firmware and sysupgrade.bin are built for the two boot methods. To identify them, a fix could be done on board name by adding a postfix "-sdboot" for SD card boot. Signed-off-by: Yangbo Lu <yangbo.lu@nxp.com>
