arm64: uaccess: Move existing GCS accessors definitions to gcs.h

Browse source

We are going to add some additional GCS access helpers to gcs.h in
order to avoid some forward reference problems with uaccess.

In preparation for that, lets move the existing gcssttr() and
put_user_gcs() routines into gcs.h where it makes sense to keep all
the accessors together. Further, the code which uses them already
includes gcs.h and there is an existing CONFIG_ARM64_GCS check we can
reuse. The GCSSTTR instruction description comment is corrected during
the move.
