configs: KASLR OPTEE RNG support for K3 devices
KASLR, or Kernel Address Space Layout Randomization, is a security
feature in the Linux kernel that randomizes the memory location
where the kernel is loaded during boot.
OP-TEE RNG is a Random Number Generator (RNG) component within the
Open Portable Trusted Execution Environment (OP-TEE) which provides
a random number to U-BOOT and U-BOOT provides this random number
as seed value to the LINUX kernel for KASLR.
Add KASLR OPTEE RNG support across K3 devices by enabling the required
configs.
