ARM: imx: Enable kaslrseed command on DH i.MX8M Plus DHCOM

Linux 6.6.y with KASLR enabled would print the following message on boot:
"
KASLR disabled due to lack of seed
"
Enable the 'kaslrseed' command so a random number seed can be pulled
from CAAM and inserted into the /chosen node 'kaslr-seed' property of
Linux kernel DT before boot, thus letting KASLR work properly.
