Oh, I see. MACH_TEGRA_GENERIC means "some Tegra SoC", and CONFIG_TEGRA*
indicate which one. Coming from my kernel background, MACH_* is a define
for a particular board, and we do have a GENERIC Tegra board, so I got
the wrong end of the stick.

I wonder if it's worth renaming CONFIG_MACH_TEGRA_GENERIC to
CONFIG_TEGRA. There don't appear to be any users of it currently.
