When fixing up the DT to report PSCI support, explicitly enable the node.
DTs may ship with the node disabled in case a PSCI implementation is not
present, and expect any PSCI implementation to enable the node if they are
actually present.

Enhance the PSCI DT editing code to allow setting a PSCI v0.2 compatible
value in the DT. The CONFIG_ option is added to the whitelist to match the
existing PSCI_1_0 option. While not adding new options to Kconfig isn't
ideal, I figure it's better to keep related options together.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Thomas reported U-Boot failed to build host tools if libfdt-devel
package is installed because tools include libfdt headers from
/usr/include/ instead of using internal ones.
This commit moves the header code:
include/libfdt.h -> include/linux/libfdt.h
include/libfdt_env.h -> include/linux/libfdt_env.h
and replaces include directives:
#include <libfdt.h> -> #include <linux/libfdt.h>
#include <libfdt_env.h> -> #include <linux/libfdt_env.h>

ATF recently began announcing PSCI v1.1. Since that version is unknown
to u-boot, the PSCI device nodes were not updated.
Switch from the case statement to a greater/less-than comparison so that
v1.1, as well as future versions, get at least the compatible nodes of
known versions.
PSCI v1.1 doesn't seem to have introduced a new corresponding compatible.

NXP/Freescale uses macro CONFIG_ARMV8_PSCI to enable their private PSCI
implementation in PPA firmware, but this macro naming too generic, so this
patch replaces it with a specic one CONFIG_FSL_PPA_ARMV8_PSCI.
And this macro CONFIG_ARMV8_PSCI will be used for a generic PSCI for ARMv8
which will be added in following patchs.

Appended the compatible strings of old version PSCI to the latest
version supported. And there are some psci functions' property must
be added to DT only for psci version 0.1, including cpu_on, cpu_off,
cpu_suspend, migrate.
Note, ARMv8 Secure Firmware Framework doesn't support PSCI ver 0.1.
