RAS: SGI: Add platform handler for RAS interrupts

Add a platform specific handler for RAS interrupts and configure the
platform RAS interrupts for EL3 handling. The interrupt handler passes
control to StandaloneMM code executing in S-EL0, which populates the
CPER buffer with relevant error information. The handler subsequently
invokes the SDEI client which processes the information in the error
information in the CPER buffer. The helper functions
plat_sgi_get_ras_ev_map and plat_sgi_get_ras_ev_map_size would be
defined for sgi platforms in the subsequent patch, which adds sgi575
specific RAS changes.

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.

calls, no matter the LOG_LEVEL value. Therefore, any variable

Even if the log output is too low for a message to be printed out on

compiler to get some type checking and validation of the format

the call to tf_log() in an always-false condition.
