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: add HAL for secure memory driver

Add hardware abstraction layer for CAAM secure memory registers. The
majority of the implementation is common to all i.MX platforms.
Only the secure memory physical address retrieve method is platform
specific.
In this commit, this method is implemented for imx8m platforms only.

drivers: caam: add manufacturing protection feature

The CAAM features a "manufacturing protection" functionality.
It is a authentication process used to authenticate the chip to
the OEM's server. The authentication process can ensure the chip:
* is a genuine NXP part
* is a correct part type
* has been properly fused
* is running a authenticated software
* runs in secure/trusted mode.
