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).

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.
