Currently for this platform resource permission is enabled and its
resources are managed by the resource permissions module.
At the same time there is no static configuration for PSCI agent should
the resource permission be turned off.
This patch adds a list of protocols that are disabled by default for
PSCI agent when there is no resource permission enabled.

The SCP firmware returned an error when an agent tries to set any
resource to its current state. This takes care of the behavior
when Uboot turns ON a resource and the kernel tries to again
enable it at boot (both are same agents on same mailbox channel).

According to the SCMIv2 spec section 4.1.4, if a command does
not exist then SCMI_NOT_FOUND must be returned. This commit
fixes this behaviour for the SCMI Performance Protocol.

This patch adds the prototype for fwk_thread_signal API.
It also adds a signal handler to the module configuration.

A signal may be used instead of an event where the target module
does not require any parameters and is not required to return any
data to the caller. It is intended as a lightweight supplement to
the standard event model, eliminating most of the overhead of
the framework event processing.

This change allows to build the SCP using LLVM for ARMv8-A
targets. The build system now calls the lld linker directly
for any LLVM build. This is due to Clang's preference to use
ld for some ARM targets, e.g. baremetal ARMv8-A. A slight
change was made to the ARMv8-A arch files to instruct lld.

This change introduces the building of the SCP firmware
using the LLVM toolchain (https://llvm.org

).
Currently the support is enabled for the target
architecture ARMv7-M and the Newlib library but it can
easily modified for other architecture targets and
standard C libraries.
