[AArch64] Implement gdbarch_core_read_description
Currently, AArch64 only have one target description which is tdesc_aarch64. So,
we haven't implemented any target description detection mechanism for core file.
This patch is an initial implementation of core_read_description method. Future
features can use this to return selected description.
gdb/
* aarch64-linux-tdep.c (aarch64_linux_core_read_description): New
function.
(aarch64_linux_init_abi): Register gdbarch_core_read_description.
