79f9b4220f lib: sbi: Fix GET_F64_REG inline assembly
Current, GET_F64_REG() macro does not generate correct inline
assembly for the RV32 systems. This patch provides separate
definitions of GET_F64_REG() macro for RV32 and RV64 systems.

0f18b3fe0a lib: Allow compiling without FP support
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.

70a474d2c2 lib: Use CSR_<FOO> instead of <foo> for csr_*()
Some older toolchains may not have all the csr's defined. Update all
the csr functions to use the CSR_ #define values instead of the
toolchain defined values.
