ARMv8/sec_firmware : Update chosen/kaslr-seed with random number

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.
