drivers: caam: sm: fix SM partition permission in SMAG registers

SM partition SMAG1 permissions were wrongly set for generating DEK blob
which results in error while decapsulating DEK blob during HAB
encrypted boot.
Setting the permissions correctly fix this issue.

drivers: caam: skip JR init of CFG_JR_HAB_INDEX

On iMX8M SoC, the HAB requires the JR0 to be set to secure world to
decrypt the kernel image when loading the image in U-Boot.

Before reaching u-boot, OP-TEE and TF-A set the JR0 to the non-secure
domain that leads to a HAB failure when trying to decrypt the kernel.

To fix the issue, this commit introduces CFG_JR_HAB_INDEX that specifies
which JR the HAB uses. OPTEE will skip the initialization of
CFG_JR_HAB_INDEX and leave it as secure.

It will also disable its usage in the device tree to inform the kernel.

drivers: caam: support querying whether prediction resistance was setup

CAAM shared descriptors initialization may happen inside OP-TEE or
beforehand, either in the bootloader or system controller.

As it's not known at compile-time whether the shared descriptors were
initialized with prediction resistance or not, OP-TEE use of the CAAM
for random number generation omitted requesting prediction resistance.

In preparation for changing that, provide a caam_hal_rng_pr_enabled()
function that queries the state of the PR bits in the shared descriptors.

core: arm: Move some DT functions to common kernel

Some existed functions for device tree in ARM could be also used for
other architectures. This commit moves most of functions from ARM
architecture into "core/kernel/dt.c", including external DT descriptor,
DT overlay, external DT initialization, API for adding DT child nodes
and reserved-memory nodes. Since "core/kernel/dt.c" is dependent with
CFG_DT, other functions which are independent with CFG_DT are put into
new file "core/kernel/boot.c".

It is a authentication process used to authenticate the chip to

* is a genuine NXP part
* is a correct part type
* has been properly fused
* is running a authenticated software
* runs in secure/trusted mode.
