  The cannot store/fetch register functions are only used for checking
if a register can be accessed using PEEKUSER/POKEUSER.
The AArch64 port doesn't support this method of access, so remove the
unused functions.

2018-11-23  Alan Hayward  <alan.hayward@arm.com>

	* linux-aarch64-low.c (aarch64_cannot_store_register): Remove.
	(aarch64_cannot_fetch_register): Likewise.
	(struct linux_target_ops): Update references.
