This block is used to generate black keys via the AES-GCM module.
The PUF KEK - feeding the AES-GCM block - is also unique for each
device.

The KEK is only available once the board has been secured via
programmable eFUSES (RSA_EN authentication via the PPK fuses).

Registering the PUF should be done using the Xilinx tools so the
adequate eFUSES are written.

drivers: clk: add devicetree support

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.

In order to keep the current mechanism simple but allow parsing the

when iterating on entries and thus avoid casting struct
dt_driver::driver to the wrong type in case a bad DT is provided. This
will also allow adding a more generic driver model by probing generic
driver based on their compatible.

core: kernel: interrupt: add type and prio for interrupts

When describing a device in the device tree, it is sometimes necessary
to parse the interrupts properties and propagates them until adding
the interrupt. For instance some interrupt-cells allows to describe
priority and type of interrupt:

interrupts = <67 IRQ_TYPE_LEVEL_HIGH 2>;

With existing support, only the interrupt number is returned by
`dt_get_irq()`. This patch adds type and prio parameter which are passed
to `dt_get_irq_type_prio()` and `itr_add_type_prio()`. This allows
interrupt drivers to fill this from devicetree in `dt_get_irq()` but also
use these information in the `add()` callback. Additionally, it allows to
specify these flags manually when not using devicetree.

These parameters can then be used by the interrupt controller driver to
setup the irq line correctly.

core_mmu: fix phys_to_virt() to check length

phys_to_virt() function without length parameter doesn`t
always have ability to find the correct mapping for
requested physical address. This is because physical
address can be mapped in the same time in different virtual
regions with different length. So the first found region
which contains the requested physical address possibly
doesn`t have enough mapped data. This is fixed by adding
the length parameter to phys_to_virt() function. Length
parameter can be set to 1 if caller knows that requested
(pa + len) doesn`t cross mapping granule boundary.

core_mmu_get_va() and io_pa_or_va() functions now are
take length parameter too as they based on phys_to_virt()
in case of MMU enabled.
