Some times gcc may generate data that is then used within code that may
be part of an efi runtime section. That data could be jump tables,
constants or strings.
In order to make sure we catch these, we need to ensure that gcc emits
them into a section that we can relocate together with all the other
efi runtime bits. This only works if the -ffunction-sections and
-fdata-sections flags are passed and the efi runtime functions are
in a section that starts with ".text".
Up to now we had all efi runtime bits in sections that did not
interfere with the normal section naming scheme, but this forces
us to do so. Hence we need to move the efi_loader text/data/rodata
sections before the global *(.text*) catch-all section.
With this patch in place, we should hopefully have an easier time
to extend the efi runtime functionality in the future.

[agraf: Fix x86_64 breakage]
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.

We dont need to keep copies of the properties that we are going to
fixup since we will be using the dtb provided by the firmware.

The firmware that runs before u-boot modifies u-boot's device tree
adding the local-mac-address and local-bd-address properties for the
compatibles "qcom,wcnss-bt" and "qcom,wcnss-wlan".
This commit reads that firmware, retrieves the properties and fixups
the device tree that is passed to the kernel before booting.

We are now using an env_ prefix for environment functions. Rename setenv()
for consistency. Also add function comments in common.h.

Otherwise the loaded image would miss the efi_runtime sections, and fall
over hard when grub (for example) tried to call runtime services located
in this section.

Add support for requesting GPIOs with a live device tree.
This involves adjusting the function signature for the legacy function

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.
