arm64: Disable ARMv8.1, ARMv8.2 architectural features
Some of the ARMv8.1, ARMv8.2 architectural features(ARM64_HW_AFDBM,
ARM64_PAN and ARM64_UAO) are enabled by default. Do not enable
these features by default, so that target specific defconfig
files can enable or disable based on features supported.
