Currently, we mandate 'F' and 'D' extension in riscv_fp.h so that
misaligned load/store emulation has access to FP registers.
The above is too restrictive and we should certainly allow compilation
for soft-FP toolchains and explicit PLATFORM_RISCV_ISA not having 'F'
and 'D' extensions.
This patch extends riscv_fp.h and misaligned load/store emulation to
allow compiling OpenSBI without FP support.

All string functions are part of libsbi. It makes more sense
to rename them to sbi_string.x as the libsbi can be linked
with external libraries that can have similar implementation.

libsbi needs some of the custom libc functions. It should be directly
included in libsbi instead of platform specific libraries.
