Use full include paths like it is done for common includes.
This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

Commit 11ad8f208d added supporting
multi-threaded CPUs on FVP platform, including modifications for
calculating CPU IDs. This patch imports the strong definition of the
same CPU ID calculation on FVP platform for TSP.
Without this patch, TSP on FVP was using the default CPU ID calculation,
which would end up being wrong on CPUs with multi-threading.

Suport for ARM GIC v2.0 and v3.0 drivers has been reworked to create three
separate drivers instead of providing a single driver that can work on both
versions of the GIC architecture. These drivers correspond to the following
software use cases:
1. A GICv2 only driver that can run only on ARM GIC v2.0 implementations
e.g. GIC-400
2. A GICv3 only driver that can run only on ARM GIC v3.0 implementations
e.g. GIC-500 in a mode where all interrupt regimes use GICv3 features
3. A deprecated GICv3 driver that operates in legacy mode. This driver can
operate only in the GICv2 mode in the secure world. On a GICv3 system, this
driver allows normal world to run in either GICv3 mode (asymmetric mode)
or in the GICv2 mode. Both modes of operation are deprecated on GICv3
systems.
ARM platforms implement both versions of the GIC architecture. This patch adds a
layer of abstraction to help ARM platform ports chose the right GIC driver and
corresponding platform support. This is as described below:
1. A set of ARM common functions have been introduced to initialise the GIC and
the driver during cold and warm boot. These functions are prefixed as
"plat_arm_gic_". Weak definitions of these functions have been provided for
each type of driver.
2. Each platform includes the sources that implement the right functions
directly into the its makefile. The FVP can be instantiated with different
versions of the GIC architecture. It uses the FVP_USE_GIC_DRIVER build option
to specify which of the three drivers should be included in the build.
3. A list of secure interrupts has to be provided to initialise each of the
three GIC drivers. For GIC v3.0 the interrupt ids have to be further
categorised as Group 0 and Group 1 Secure interrupts. For GIC v2.0, the two
types are merged and treated as Group 0 interrupts.
The two lists of interrupts are exported from the platform_def.h. The lists
are constructed by adding a list of board specific interrupt ids to a list of
ids common to all ARM platforms and Compute sub-systems.
This patch also makes some fields of `arm_config` data structure in FVP redundant
and these unused fields are removed.

This patch migrates ARM reference platforms, Juno and FVP, to the new platform
API mandated by the new PSCI power domain topology and composite power state
frameworks. The platform specific makefiles now exports the build flag
ENABLE_PLAT_COMPAT=0 to disable the platform compatibility layer.

Move the FVP port from plat/fvp to plat/arm/board/fvp. Also rename
some of the files so they are consistently prefixed with fvp_.
Update the platform makefiles accordingly.
