Add support for Tegra124 Nyan. Pinmux is based on norrin with a single

Allen, can you please confirm the reset GPIO setting for Norrin in the
pinmux patch you sent? It seems as if the two boards truly are this
identical, the reset pin would be too.
Well Nyan and Norrin *are* identical - they're different names for the
same board.
Oh. It's a bit of an epic fail to have multiple names for the exact same
thing:-(
When you say Nyan, are you talking about Nyan the family of boards (of
which Big is one member), or do you consider Nyan to be a single board?
Olof previously told me that Nyan was a family, of which Big was a
member. So, I'm not sure if Norrin is another name for the family, or
another name for a specific member.
It seems from the other patches though that this is for
Big (in which case the name of the config file should reflect that).
Yes. All of the kernel, U-Boot, and tegra-pinmux-scripts (and
tegra-uboot-flasher if relevant) should use the exact same name for the
board. If what's currently known as Norrin in tegra-pinmux-scripts
should actually be called Nyan or Nyan-big, we should rename it.
Either way, the reset GPIO (PI5) is configured the same across all
Nyan-based boards (Nyan/Norrin, Big, Blaze, Kitty) and I believe what
Simon has here is correct.
If the entire pinmux identical across all of those boards too, or does
it just happen that's true for this one pin?
Hopefully Allen can comment on why the current Norrin values in
tegra-pinmux-scripts differ then. I do recall that Venice2 had a similar
issue, where the spreadsheet was actually wrong and SW had been fixed
without updating the spreadsheet (grrr...) Perhaps the situation here is
that simple too.
