The whole gnu-efi project is licensed under BSD license, see [1].
However some of the RISC-V codes have conflict license identifiers:
- Some mention GPL-2.0+ in the SPDX license part, but the long license
header indicates it's actually BSD and GPL-2.0+ dual-licensed
- Some mention GPL-2.0+ in the SPDX license part only
- Some do not have any license indication
To have a matching license with the whole project, this commit updates
all RISC-V codes to have the correct SPDX license identifiers
(GPL-2.0+ or BSD dual-license).

The assembly code uses fixed offsets into the jmp_buf and leaves an 8 byte
gap between the GPRs and the FPRs, but the jmp_buf structure was not laid
out to account for this so the code would overrun the jmp_buf by 8 bytes.

There's little reason not to derive the RISCV64 version of efibind.h
from the AARCH64 version, especially as the current version is missing
required macros such as EFI_DRIVER_ENTRY_POINT() which breaks the
compilation of some drivers.
The only major difference we introduce from AARCH64 is to consider
that any toolchain that supports RISCV64 is modern enough to support
<stdint.h>. Also, as we preserve the added definition for BOOLEAN,
we guard it with an ifndef in anticipation of MSVC RISCV64 support.
We validated these changes by confirming that they now allow gnu-efi
to be used to compile a set of UEFI drivers for RISCV64.
Add definitions for the EFI device tree table, as specified in UEFI
specification 2.9 (March 2021).

The hidden visibility #pragma in inc/arm/efibind.h was meant to inform
the compiler that symbols with external linkage are never exported from
shared libraries [and thus never preempted] when executing in UEFI context
(since UEFI does not support shared libraries). This allows the compiler to
generate relative symbol references instead of GOT entries, which is much more
efficient since the latter need to be relocated before invoking the entry
point of the UEFI app.
However, as it turns out, this pragma is leaking into other code that does
not run in UEFI context, but simply needs to access data structures that
UEFI defines. So make the pragma dependent on whether we are building with
-ffreestanding, which is only used for bare metal code such as UEFI.

Having to add specific arch include paths and then <gnu-efi>/lib
to be able to use gnu-efi in an application is annoying.
This patch ensures that the library itself takes care of including
the relevant headers, and that one needs only to add <gnu-efi>/inc
in their include path to be able to use gnu-efi.
Per https://github.com/tianocore/edk2/blob/master/MdePkg/Include/Library/PrintLib.h
AsciiPrint() is the official name of APrint() so declare it as such and define
an APrint alias for compatibility.
Also add an AsciiVSPrint() to print a formatted ASCII string to a buffer using
a va_list. AsciiPrint() too is defined in EDK2's PrintLib.h, though our implementation
just invokes the Unicode version and then converts the buffer to ASCII.
The __builtin_va_###() intrinsics apply only to GCC-like compilers and
MSVC's <stdarg.h> works just fine with gnu-efi.
Without this patch, one has to define GNU_EFI_USE_EXTERNAL_STDARG to
make gnu-efi work with a Microsoft toolchain, which is annoying...
As EFI_SHELL_PARAMETERS_PROTOCOL is also defined in UEFI Shell Spec,
put it together with EFI_SHELL_PROTOCOL.

* __STDC_VERSION__ is undefined when headers are called from C++
code resulting in not using stdint.h and efibind.h
"making a guess" on what they are. extern "C" will not define
__STDC_VERSION__.
* Always leverage stdint.h on C++.
* Honestly, gnu-efi should always use stdint.h, or find a better
way to detect it. (or platforms without it need to catch up to 2007)
Breaks gcc builds with '-nostdinc' flag.
The fix in 1a53d8f88a
(Fix for problem with undeclared intptr_t type), which is also merged
fixes the same problem, without causing breakage.
This reverts commit 6335e5c697.
