core: firewall: add firewall framework

Add a generic firewall controller framework. The goal of this framework
is to offer access control and configuration APIs, that are implemented
in the firewall controllers drivers, to the firewall consumers. This
framework requires an embedded device tree.

A firewall controller is an access controller [1]. It should register
itself as a provider to the framework. Firewall controllers have the
possibility to populate their bus according to defined firewall accesses
defined in the "access-controllers" property in each of the device's
node.

Any device that consumes one or more firewall should refer it/them in
their "access-controllers" property. Arguments can be passed along with
the phandle of the firewall controller(s).

drivers: clk: replace clock main spinlock with a mutex

Change clock framework lock from an interrupts masked spinning lock
to a mutex. This allows the clock framework to better handle slow
stabilizing clocks as PLLs without masking the system interrupt
which can have side effects on the REE or even the TEE.

To support clock accesses during low power state transition sequences
while non-secure world is no operating, the lock is not taken when
the execution is not in the scope of a TEE thread.

This change is not expected to impact supported platforms that currently
only access clock operation from thread contexts or atomic PM sequences.

Implement a simple console driver which uses semihosting operations to

that host side file.
- If the caller of semihosting_console_init() does not provide the path
of the file, the driver will connect the console to the host debug
console directly.

If CFG_SEMIHOSTING_CONSOLE is enabled, OP-TEE will try to initialize the
