RAS: Introduce handler for EL3 EAs

External Aborts while executing in EL3 is fatal in nature. This patch
allows for the platform to define a handler for External Aborts received
while executing in EL3. A default implementation is added which falls
back to platform unhandled exception.

RAS: Introduce handler for Double Faults

Double fault is when the PE receives another error whilst one is being
handled. To detect double fault condition, a per-CPU flag is introduced
to track the status of error handling. The flag is checked/modified
while temporarily masking external aborts on the PE.

This patch routes double faults to a separate platform-defined handler.

RAS: Introduce handler for Uncontainable errors

Uncontainable errors are the most severe form of errors, which typically
mean that the system state can't be trusted any more. This further means
that normal error recovery process can't be followed, and an orderly
shutdown of the system is often desirable.

This patch allows for the platform to define a handler for Uncontainable
errors received. Due to the nature of Uncontainable error, the handler
is expected to initiate an orderly shutdown of the system, and therefore
is not expected to return. A default implementation is added which falls
back to platform unhandled exception.

Also fix ras_arch.h header guards.

Fix types of arch.h definitions

Define the values as unsigned int or unsigned long long based on the
actual size of the register. This prevents subtle issues caused by
having a type that is too small. For example:

#define OPTION_ENABLE 0x3
#define OPTION_SHIFT 32

uint64_t mask = OPTION_ENABLE << OPTION_SHIFT;

Because OPTION_ENABLE fits in an int, the value is considered an int.
This means that, after shifting it 32 places to the left, the final
result is 0. The correct way to define the values is:

#define OPTION_ENABLE ULL(0x3)
#define OPTION_SHIFT U(32)

In this case, the compiler is forced to use a 64 bit value from the
start, so shifting it 32 places to the left results in the expected
value.
