riscv: misaligned: declare misaligned_access_speed under CONFIG_RISCV_MISALIGNED

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.
