For FTRACE_WITH_REGS, we're going to want to generate a MOV (register) instruction as part of the callsite intialization. As MOV (register) is an alias for ORR (shifted register), we can generate this with aarch64_insn_gen_logical_shifted_reg(), but it's somewhat verbose and difficult to read in-context. Add a aarch64_insn_gen_move_reg() wrapper for this case so that we can write callers in a more straightforward way.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
