arm64: zynqmp: Enable the config CMD_KASLRSEED
Kernel Address Space Layout Randomization (KASLR) is a hardening
feature that aims to make it more difficult to take advantage
of known exploits in the kernel, by placing kernel data structures
at a random address at each boot.The bootloader supports randomizing
the virtual address at which the kernel image is loaded.
The bootloader must provide entropy by passing a random u64 value
in the /chosen/kaslr-seed device tree node.
When we run "kaslrseed" command from U-Boot, the bootloader will
genarate the kaslr-seed and update the /chosen/kaslr-seed DT property.
