arm64: disable ARM64_ERRATUM_843419 for clang LTO 



CONFIG_LTO_CLANG depends on GNU gold, which can generate ADR_PREL_PG_HI21
relocations with --fix-cortex-a53-843419, even when -code-model=large has
been passed to LLVMgold.

Since ARM64_ERRATUM_843419 disables kernel support for these relocations,
disable the erratum when LTO is used.
