tegra210: use UTF-8, not ISO-8859

[emaste]

Summary

Prompted by "This is a binary file." in D43192 I had a look at sys/arm64/nvidia/tegra210/tegra210_xusbpadctl.c, which had an ISO-8859 μ. Convert to Unicode/UTF-8.

(Click on View Options and change to UTF-8)

Thanks, but I think that this is not supposed to be a Chinese char but just "20 sec Lock time", @mmel ?

Maximum PLL lock time is 20 microsecond. Alternatively, we may use the 'us' to avoid UTF-8 in source files.

Phabricator gets confused when the encoding is different between the before & after versions so you have to pick UTF-8 manually. Once done the right side looks like:

We have some UTF-8 files in the tree already and I think μ is fine.
