core: fix objectUsage handling for persistent objects

Before this patch was the object usage field stored in the
non-persistent part of an object handle, regardless of whether the
storage object was persistent. This prevents updates to this field from
being restored the next time the persistent object is opened. Updates to
the field are also not replicated to eventual other open handles for the
object. Fix this by storing the "usage" bits in a new obj_info_usage
field in struct tee_pobj for persistent objects. Updates to the field
are also written into secure storage to preserve the content the next
time the object is opened.

core: gic: add gic_init_donate_sgi_to_ns()

Adds gic_init_donate_sgi_to_ns() which changes a secure SGI to become
non-secure.

Secure world currently has a few SGIs to spare while normal world
typically have reserved each of the non-secure SGIs for different
purposes.

In case another non-secure SGI is needed secure world can donate one of
its unused SGIs. This configuration will then deviate from the standard
GIC configuration where SGI ID0-ID7 are non-secure and ID8-ID15 are
secure.

Platforms using gic_init_donate_sgi_to_ns() should also use
gic_init_per_cpu() instead of the deprecated gic_cpu_init().

core: interrupt: registering interrupt providers

Adds interrupt chip framework API functions for an interrupt controller
to register as an interrupt provider in the driver probing sequence
based on device tree. This allows interrupt consumer to be deferred
when a dependent interrupt controller is not yet initialized.

Interrupt controllers register a driver in DT_DRIVER providers list
with: interrupt_register_provider().

Interrupt consumer can get their interrupt through DT data with
interrupt_dt_get(), interrupt_dt_get_by_index() or
interrupt_dt_get_by_name().

This change removes inclusion of interrupt.h from kernel/dt.h as it is
not needed and conflicts with inclusion of kernel/dt.h from
kernel/interrupt.h.
