[U-Boot] [PATCH] tegra2: move tegra2 SoC code to arch/arm/cpu/tegra2-common

In preparation for splitting out the armv4t code from tegra2, move the
tegra2 SoC code to arch/arm/cpu/tegra2-common. This code will be
compiled armv4t for the arm7tdmi and armv7 for the cortex A9.

Resending this with "git format-patch -M" to make it more readable
and removing cover letter
This is part of an upcoming patch set to move all armv4t code out of
tegra2 u-boot and put it into an SPL, but I wanted to get some early
feedback on this patch. This moves most of the tegra2 SoC code from
arch/arm/cpu/armv7 to a new directory arch/arm/cpu/tegra2-common.
This code will be shared between the armv7 and armv4t builds of
tegra2.
