[ARM] S3C64XX: Initial arch header files
Add the initial header files for the S3C64XX support to satisfy the
minimal requirements to build a kernel. Some definitions will therefore
be placeholders or empty functions that will ensure that the system can
build and have base functionality. These will be filled in at a later
date.
