[AArch64] Simplify aarch64_can_eliminate

Simplify aarch64_can_eliminate - if we need a frame pointer, we must
eliminate to HARD_FRAME_POINTER_REGNUM.  Rather than hardcoding all
combinations from the ELIMINABLE_REGS list, just do the correct check.

    gcc/
	* config/aarch64/aarch64.c (aarch64_can_eliminate): Simplify logic.
