Enabling V-extension using -march option causes OpenSBI boot-time
hang with LLVM compiler.
As a work-around, don't enable V-extension using -march option and
instead use a custom OpenSBI specific define inform availability of
V-extension to lib/sbi/sbi_trap_v_ldst.c.

Add misaligned load/store handling for the vector extension
to the sbi_misaligned_ldst library.
This implementation is inspired from the misaligned_vec_ldst
implementation in the riscv-pk project.
