ARM: tegra: Default configuration changes for v5.9-rc1

Enables a few new configuration options that are useful on the new Nexus
7 and Acer A500 devices, as well as the userspace CPU frequency governor
that's mainly used for testing.

I've pulled all the other branches, but I'm a little bit wary about
this one since
Dmitry's patch enables a number of options that would increase the kernel
size, and I see no indication that it has been reviewed by anyone else.

I think the changes all make sense, but I would prefer to have a wider
audience for that patch and get some Acks. If you like, you can send the
tegra specific changes in a new pull request in the meantime, and then
send the remaining additions to the usual suspects as an RFC, with
Cc:soc@kernel.org, so I can apply it later if everyone is happy enough
with it.

      Arnd

Hello, Arnd!

But these are already the tegra specific changes. The patch changes
tegra_defconfig and not the multi_v7_defconfig.

Could you please clarify from whom would you expect to get more Acks if
not from the tegra maintainers?

In practice nobody uses upstream defconfig as-is, it's only used as
initial template. So I'm not sure why tegra-kernel size makes you to
worry. Could you please explain?

It was a mistake on my end, for some reason I thought you were
changing the arm64 defconfig, which does not have per-platform
files.

The patch is good, and I'll pull the branch as soon as I get to it
(it's a bit late for today).
