Basic fault mitigation routines

Adds basic fault mitigation routines designed to help protecting from
fault injection attacks on the hardware. This is by no means bullet
proof, but it should at least improve the situation.

These routines focus on verifying that a function has been called and
that the returned value matches the result from the function. This is
done by having a handshake between the caller and the callee where also
the return value is transmitted in a separate channel.

core: ffa: remove pager annotations

Configuration with pager and FF-A is currently not supported. Supporting
this would require extensions to the FF-A specification to be able to
load OP-TEE with paging enabled. So far we don't have any platforms with
FF-A which are memory constrained enough that paging can be motivated. If
this would change we'll have a good use case to test with when adding
pager support for FF-A.

Currently we have a few pager annotations (DECLARE_KEEP_PAGER() and
__*_unpaged) which are effectively unused. So save us from adding yet
more unused annotations by removing the few we have in the FF-A specific
code.

exit and next entry. Therefore this change loads and saves that register
into StMM context from stmm_enter_user_mode() while in thread entry
