zynqmp: drivers: generate HUK from PUF KEK

If authenticated boot was disabled we allow generating the HUK using
the SHA-256 of the DNA unique identifier.

If authenticated boot was enabled, use the PUK KEK to generate the
HUK instead. The PUF KEK must be registered while securing the board
using the Xilinx tools. In this case, the HUK is generated by reading
the DNA eFuses. This 96 bits value is used to generate a 16 byte
digest which is then AES-GCM encrypted using the PUF KEK. The
resulting 16 byte value is the HUK. To prevent the HUK from being
leaked, the AES-GCM module must be reserved.

The HUK generation was validated on Zynqmp zu3cg using the Xilinx
Lightweight Provisioning Tool to enable authenticated boot and to
provision the PUF (burning a number of eFuses in the process).

To access eFuses, PMUFW should be built with -DENABLE_EFUSE_ACCESS=1.

Notice however that certain eFuses will not be available unless the
Xilskey library linked to the PMUFW is compiled removing some of those
security restrictions.

zynqmp: drivers: AES-GCM with PUF KEK

Provide a mechanism to encrypt a red key using the KEK; the KEK is
only available on secured boards after the RSA_EN and PPK eFUSES have
been burnt (the system will only boot ROM authenticated bootloaders
from here on).

The main use case for OP-TEE would be to encode the zynqmp per device
unique identifier (DNA0, DNA1, DNA2 eFUSEs - ie, a red key) using the
KEK. The encryption key generated this way is cryptographically strong
and will be used as the device HUK (ie, black key).

Test code:

csu_aes_encrypt_data(src, dst, BLOB_DATA_SIZE, tag, GCM_TAG_SIZE,
iv, GCM_IV_SIZE, CSU_AES_KEY_SRC_DEV);
csu_aes_decrypt_data(dst, src, BLOB_DATA_SIZE, tag, GCM_TAG_SIZE,
iv, GCM_IV_SIZE, CSU_AES_KEY_SRC_DEV);
if (memcmp(src, buffer, BLOB_DATA_SIZE)) {

When using a devicetree, it is often useful to have clocks parsing.
This support adds clocks properties parsing and allow having clock
providers and users. Clocks drivers can also be declared with
CLK_DT_DECLARE. They will be probed automatically by the clock core.
On the user side, function clk_dt_get_by_name and clk_dt_get_by_idx
allows to retrieve a clock from the device tree description and match
it with the provider clocks. The core ensure the clocks are probed
hierarchically.
This support is enabled using CFG_DRIVERS_CLK_DT.
