xtensa: Remove an unnecessary constraint modifier from movsf_internal insn pattern

In this case, there is no need to consider reloading when memory is the
destination.  On the other hand, when memory is the source, reloading
read from constant pool becomes double indirection and should obviously
be avoided.

gcc/ChangeLog:

* config/xtensa/xtensa.md (movsf_internal):
Remove destination side constraint modifier '^' in the third
alternative.
