xtensa: Remove TARGET_MEMORY_MOVE_COST hook
It used to always return a constant 4, which is same as the default
behavior, but doesn't take into account the effects of secondary
reloads.
Therefore, the implementation of this target hook is removed.
gcc/ChangeLog:
* config/xtensa/xtensa.cc
(TARGET_MEMORY_MOVE_COST, xtensa_memory_move_cost): Remove.
