Currently the debugfs output for pinctrl-amd puts the first line
combined with "GPIO bank". This makes it a little harder to process
as the file needs to be manually corrected for the mistake.
Change this to be a new line character instead.

The output is currently split across two lines making it more
difficult to parse unless the newlines are removed between pins
or it's read in by a parser like Libreoffice Calc or Google docs.
To make it easier to follow to the naked eye in a terminal window:
* drop the newline in the middle of pin definitions
* shorten all output using unicode characters
* align all pipe delimitters
* output the same phrase even for disabled functions
(but with a ∅ character)

That's a bit unorthodox, what happens when someone uses their
old VT100 terminal to look at this file?
BIUT! It is a debugfs file, and you folks at AMD are going to be
using this and I just assume that you folks have aligned internally
that this is how you want things so I just applied this.
We need testing in linux-next for this anyway, the merge window
is close. If the other AMD people don't like it for some reason
I can always pull it out.
Yours,
Linus Walleij

I guess it would look pretty terrible, but given it's debugfs very
unlikely.

I didn't pre-align this with the other AMD guys. It was just something
I noticed that has annoyed me as I look at bugs that I'm looking at and
since it's not sensitive content figured public review is fine for it.
That's why I left them on To: line. But yes as you say if others don't like
it reverts are cheap and it's better to have enough time for good testing
coverage.
Thanks!
