[PATCH 1/2] arm64: Kconfig: add basic support for the Tegra SoC family and the Tegra132 SoC

[Paul Walmsley <paul-DWxLp4Yu+b8AvxtiuMwx3w@public.gmane.org>]

Add basic Kbuild support for the Tegra SoC family, and specifically,
the Tegra132 SoC.  Tegra132 pairs the NVIDIA Denver CPU complex with
the SoC integration of Tegra124 - hence the use of ARCH_TEGRA and the
Tegra124 pinctrl option.

For the time being, Tegra ARM64 support is added with a dependency on
CONFIG_BROKEN.  This is temporary and can be removed when the
following two patches for compilation failures have been merged:

"soc: tegra: pmc: restrict compilation of suspend-related support to ARM"
https://git.kernel.org/cgit/linux/kernel/git/pjw/tegra-dev.git/commit/?id=053decbf3900d4e8fee799f9a29cf8d905b2fcb1

"clocksource: tegra: wrap arch/arm-specific sections in CONFIG_ARM"
https://git.kernel.org/cgit/linux/kernel/git/pjw/tegra-dev.git/commit/?id=220aa7fcc74a1a089916be6cb34b0e326f31841f

This patch was based on a patch originally written by Allen Martin
<amartin-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>.
