core: introduce scall layer from svc parts

Introduces a scall layer by renaming various thread_svc* names and
_*handle_svc() functions and function pointers as a first step in doing
architecture neutral syscall processing.

The name scall is used instead of syscall since the syscall_ prefix is
reserved for the functions implementing the actual syscall. While scall
is the infrastructure used to reach the syscall functions.

No files are renamed and removed at this stage. This patch doesn't
change any behaviour.

where some clocks are optional. These functions return such error code
since commit [1].

This driver uses the PLM xilpuf service to deliver the physical
unclonable function (PUF).

The Physical unclonable function (PUF) generates two device unique
signatures per die. One signature is used for the key encryption key
(KEK) and one signature is used as an unique identification value.

The Unique ID is fully accessible and its value can be cleared
(hidden) and regenerated.

The KEK is never accessible and only usable from the AES-GCM engine.
