drivers: add reset controller framework

Adds a common reset controller framework rstctrl for interfacing
reset controllers exposed by a platform.

Reset controller consumers can act on relate reset level with
rstctrl_assert(), rstctrl_deassert() and friends.

Reset controller consumers can claim exclusive access to the reset
level woth rstctrl_get_exclusive(), rstctrl_put_exclusive().

Reset controller provider drivers call rstctrl_register_provider()
to allow other drivers to get a reset control reference from
a devicetree reference. Reset controller driver are identified with
type DT_DRIVER_RSTCTRL.

A reset controller provider exposes struct rstctrl instances made of
an opaque private reference (a private data pointer or an unsigned
integer identifier), an reset controller operators reference and
the exclusive claim state.

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).

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,
