riscv: Update SPDX license identifiers

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).

riscv: Fix ld RWX warning

The current ld script places .dynamic section right after .text, which
results in that one LOAD segment contains both data and code. Binutils
2.39 and later will throw a warning if RWX segments exist. Code and
data should be placed in different LOAD segments with different
permissions. This patch adds a gap between data and code sections which
is taken from the default ld script in riscv64.

According to README.gnuefi,

To build the sample EFI applications provided in subdirectory "apps",
simply invoke "make" in the toplevel directory (the directory
containing this README file). This should build lib/libefi.a and
gnuefi/libgnuefi.a first and then all the EFI applications such as a
apps/t6.efi.

The default target of top directory Makefile should be all instead of
gnuefi.

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.
