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.

drivers: clk: add generic clock framework

In order to ease clock support in OP-TEE, add a generic clock framework
which allows to add clocks driver and handle clock hierarchy.
This clock framework provides various functions to enable/disable clock
and to get their rate. Some basic behavior are supported such as gating
when parent or rate is set. This option is enabled using
CFG_DRIVERS_CLK which is disabled by default.

drivers: add type field to dt_driver struct

In order to keep the current mechanism simple but allow parsing the
device tree by iterating on driver (clocks for instance), add a type
field to dt driver struct which will allow differentiating drivers
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.
