gdbserver: AArch64: Remove cannot_fetch/store_register
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. gdb/gdbserver: * linux-aarch64-low.c (aarch64_cannot_store_register): Remove. (aarch64_cannot_fetch_register): Likewise. (struct linux_target_ops): Update references.
