This changes system reboot for socfpga to issue a cold reboot by default instead of a warm reboot. Warm reboot can still be used by setting reboot_mode to REBOOT_WARM (e.g. via kernel command line 'reboot='), but this patch ensures cold reboot is issued for both REBOOT_COLD and REBOOT_HARD. Also, cold reboot is more fail safe than warm reboot has some issues at least fo CSEL=0 and BSEL=qspi, where the boot rom does not set the qspi clock to a valid range.

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.
