Arm platforms: Remove common RAS configuration source

The file arm_ras.c intended to provide common platform-specific RAS
configuration for Arm platforms. Because this file has symbol
definitions, it's proving difficult to provide a common definition.

This patch therefore renames and makes the file specific to FVP. Other
platforms shall provide their own configuration in similar fashion.
