arm64: first set of Kconfig patches for Tegra132 support

Hi Catalin & Will,

These patches start the ARM64 Kconfig and defconfig changes to support the Tegra132 (aka Tegra K1 64-bit) SoC and the NVIDIA Norrin64 FFD board.

Tegra132 support is made conditional on CONFIG_BROKEN, since there are some patches pending for other maintainers to fix compilation when CONFIG_ARCH_TEGRA is set during an ARM64 build. Once those patches have been merged, a subsequent patch will be sent to remove the CONFIG_BROKEN dependency and to make a few other defconfig changes that are dependent on CONFIG_ARCH_TEGRA.

These patches apply on the arm64 fixes/core branch, commit 5d96e0cba263. They have been boot-tested on QEMU 2.2.0 AArch64, and (after other patches have been applied) have been boot-tested on the Tegra132 Norrin64 FFD board.

A signed tag containing these patches is available at:
