Add CPU specific crash reporting handlers
This patch adds handlers for dumping Cortex-A57 and Cortex-A53 specific register
state to the CPU specific operations framework. The contents of CPUECTLR_EL1 are
dumped currently.

Add CPUECTLR_EL1 and Snoop Control register to crash reporting
This patch adds the CPUECTLR_EL1 register and the CCI Snoop Control
register to the list of registers being reported when an unhandled
exception occurs.

Rework the crash reporting in BL3-1 to use less stack
This patch reworks the crash reporting mechanism to further
optimise the stack and code size. The reporting makes use
of assembly console functions to avoid calling C Runtime
to report the CPU state. The crash buffer requirement is
reduced to 64 bytes with this implementation. The crash
buffer is now part of per-cpu data which makes retrieving
the crash buffer trivial.
Also now panic() will use crash reporting if
invoked from BL3-1.
Fixes ARM-software/tf-issues#199

Per-cpu data cache restructuring
This patch prepares the per-cpu pointer cache for wider use by:
* renaming the structure to cpu_data and placing in new header
* providing accessors for this CPU, or other CPUs
* splitting the initialization of the TPIDR pointer from the
initialization of the cpu_data content
* moving the crash stack initialization to a crash stack function
* setting the TPIDR pointer very early during boot

Make the BL3-1 crash reporting optional
This patch makes the console crash dump of processor register
state optional based on the CRASH_REPORTING make variable.
This defaults to only being enabled for DEBUG builds. This can
be overridden by setting a different value in the platform
makefile or on the make command line.

Include 'platform_def.h' header file in 'crash_reporting.S'
'crash_reporting.S' needs to include 'platform_def.h' to get the
definition of PLATFORM_CORE_COUNT.
Note: On FVP it was compiling because 'platform_def.h' gets included
through 'plat/fvp/include/plat_macros.S' but we don't want to rely on
that for other platforms.

Rework BL3-1 unhandled exception handling and reporting
This patch implements the register reporting when unhandled exceptions are
taken in BL3-1. Unhandled exceptions will result in a dump of registers
to the console, before halting execution by that CPU. The Crash Stack,
previously called the Exception Stack, is used for this activity.
This stack is used to preserve the CPU context and runtime stack
contents for debugging and analysis.
This also introduces the per_cpu_ptr_cache, referenced by tpidr_el3,
to provide easy access to some of BL3-1 per-cpu data structures.
Initially, this is used to provide a pointer to the Crash stack.
panic() now prints the the error file and line number in Debug mode
and prints the PC value in release mode.
The Exception Stack is renamed to Crash Stack with this patch.
The original intention of exception stack is no longer valid
since we intend to support several valid exceptions like IRQ
and FIQ in the trusted firmware context. This stack is now
utilized for dumping and reporting the system state when a
crash happens and hence the rename.
Fixes ARM-software/tf-issues#79 Improve reporting of unhandled exception
