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
