arm64: Add missing Falkor part number for branch predictor hardening

arm64: Add missing Falkor part number for branch predictor hardening

commit 16e574d762ac5512eb922ac0ac5eed360b7db9d8 upstream.

References to CPU part number MIDR_QCOM_FALKOR were dropped from the
mailing list patch due to mainline/arm64 branch dependency. So this
patch adds the missing part number.
