Kai-Heng Feng d60cd06331 PM: ACPI: reboot: Use S5 for reboot
After reboot, it's not possible to use hotkeys to enter BIOS setup
and boot menu on some HP laptops.

BIOS folks identified the root cause is the missing _PTS call, and
BIOS is expecting _PTS to do proper reset.

Using S5 for reboot is default behavior under Windows, "A full
shutdown (S5) occurs when a system restart is requested" [1], so
let's do the same here.

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.
