Add common ARM and CSS platform code This major change pulls out the common functionality from the FVP and Juno platform ports into the following categories: * (include/)plat/common. Common platform porting functionality that typically may be used by all platforms. * (include/)plat/arm/common. Common platform porting functionality that may be used by all ARM standard platforms. This includes all ARM development platforms like FVP and Juno but may also include non-ARM-owned platforms. * (include/)plat/arm/board/common. Common platform porting functionality for ARM development platforms at the board (off SoC) level. * (include/)plat/arm/css/common. Common platform porting functionality at the ARM Compute SubSystem (CSS) level. Juno is an example of a CSS-based platform. * (include/)plat/arm/soc/common. Common platform porting functionality at the ARM SoC level, which is not already defined at the ARM CSS level. No guarantees are made about the backward compatibility of functionality provided in (include/)plat/arm. Also remove any unnecessary variation between the ARM development platform ports, including: * Unify the way BL2 passes `bl31_params_t` to BL3-1. Use the Juno implementation, which copies the information from BL2 memory instead of expecting it to persist in shared memory. * Unify the TZC configuration. There is no need to add a region for SCP in Juno; it's enough to simply not allow any access to this reserved region. Also set region 0 to provide no access by default instead of assuming this is the case. * Unify the number of memory map regions required for ARM development platforms, although the actual ranges mapped for each platform may be different. For the FVP port, this reduces the mapped peripheral address space. These latter changes will only be observed when the platform ports are migrated to use the new common platform code in subsequent patches. Change-Id: Id9c269dd3dc6e74533d0e5116fdd826d53946dc8

* Some of the platform porting definitions use the 'ull' suffix in order to

*
* The TSP linker script includes some of these definitions to define the BL3-2
* memory map, but the GNU LD does not support the 'ull' suffix, causing the
* build process to fail. To solve this problem, the auxiliary macro MAKE_ULL(x)
* will add the 'ull' suffix only when the macro __LINKER__ is not defined
* (__LINKER__ is defined in the command line to preprocess the linker script).
* Constants in the linker script will not have the 'ull' suffix, but this is
* not a problem since the linker evaluates all constant expressions to 64 bit
* (assuming the target architecture is 64 bit).
