arm64: versal-net: Enable the config CMD_KASLRSEED

Browse Source 
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.
