arm-tdep.c: Remove unused arm_displaced_step_copy_insn

This function is never used, since it is superseded by
arm_linux_displaced_step_copy_insn.

gdb/ChangeLog:

	* arm-tdep.c (arm_displaced_step_copy_insn): Remove.
	(ARM displaced stepping support): Remove reference to
	arm_displaced_step_copy_insn in comment.
	* arm-tdep.h (arm_displaced_step_copy_insn): Remove.
	* arm-linux-tdep.c (arm_linux_displaced_step_copy_insn): Remove
	reference to arm_displaced_step_copy_insn in comment.

    Generally ARM displaced stepping works as follows:
 
    1. When an instruction is to be single-stepped, it is first decoded by
-      arm_process_displaced_insn (called from arm_displaced_step_copy_insn).
-      Depending on the type of instruction, it is then copied to a scratch
-      location, possibly in a modified form.  The copy_* set of functions
-      performs such modification, as necessary.  A breakpoint is placed after
-      the modified instruction in the scratch space to return control to GDB.
-      Note in particular that instructions which modify the PC will no longer
-      do so after modification.
