fix(stm32mp1): fix enum prints

With gcc-11, the -Wformat-signedness warning complains about enum values
that should be printed as unsigned values. But the current version of
compiler used in CI states that this parameter is signed. Just cast the
value then.

Introduce helper functions stm32mp_register_secure_gpio() and
stm32mp_register_non_secure_gpio() for drivers to register a
GPIO pin as secure or non-secure.

These functions are stubbed when shared resource driver is not
embedded in the BL image so that drivers do not bother whether they
shall register or not their resources.

Define helper functions stm32mp_register_secure_periph() and
stm32mp_register_non_secure_periph() for platform drivers to
register a shared resource assigned to respectively secure
or non-secure world.

Some resources are related to clock resources. When a resource is
registered as secure, ensure its clock dependencies are also
registered as secure. Registering a non-secure resource does not
mandate its clock dependencies are also registered as non-secure.

stm32mp1: shared resources: apply registered configuration

BL32/SP_MIN configures platform security hardening from the shared
resources driver. At the end of SP_MIN initialization, all shared
resources shall be assigned to secure or non-secure world by
drivers. A lock prevent from further change on the resource
assignation. By definition, resources not registered are assign
to non-secure world since not claimed by any component on the BL.

No functional change as all resources are currently in state
SHRES_UNREGISTERED hence assigned to non-secure world as prior
this change in stm32mp1_etzpc_early_setup() and
sp_min_platform_setup().

stm32mp1: introduce shared resources support

STM32MP1 SoC includes peripheral interfaces that can be assigned to
the secure world, or that can be opened to the non-secure world.

This change introduces the basics of a driver that manages such
resources which assignation is done at run time. It currently offers
API functions that state whether a service exposed to non-secure
world has permission to access a targeted clock or reset controller.
