While misaligned_access_speed was defined in a file compile with CONFIG_RISCV_MISALIGNED, its definition was under CONFIG_RISCV_SCALAR_MISALIGNED. This resulted in compilation problems when using it in a file compiled with CONFIG_RISCV_MISALIGNED.
Move the declaration under CONFIG_RISCV_MISALIGNED so that it can be used unconditionnally when compiled with that config and remove the check for that variable in traps_misaligned.c.
