of the EFI binary.

When building with binutils 2.39 warnings
*_efi.so has a LOAD segment with RWX permissions
occur.
Use SHF_WRITE | SHF_ALLOC as section flags for the .data section.

While our EFI binaries execute without problems on EDK II they crash on
a Lenovo X13s. Let our binaries look more like what EDK II produces:
* move all writable data to a .data section
* align sections to 4 KiB boundaries (matching EFI page size)
* remove IMAGE_SCN_LNK_NRELOC_OVFL from .reloc section flags

The alignment of sections in the EFI binaries generated by U-Boot is
incorrect.
According to the PE-COFF specification [1] the minimum value for
FileAlignment is 512. If the value of SectionAlignment is
less then the page size, it must equal FileAlignment.
Let's set both values to 512 for the ARM and RISC-V architectures.

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.
