kASLR support in kernel requires a random number to be passed via chosen/kaslr-seed propert. sec_firmware generates this random seed which can then be passed in the device tree node. sec_firmware reserves JR3 for it's own usage. Node for JR3 is removed from device-tree. Signed-off-by: Ruchika Gupta <ruchika.gupta@nxp.com>
