I usually prefer 'depends on' in a case like this, but it doesn't make
a huge difference. If we end up using 'select' here, we should
make the other symbol invisible though.

This change helps, but feels a little unclean. It also prevents us
from adding a '|| COMPILE_TEST' dependency.

How about making PHY_TEGRA_XUSB silent, and adding the 'select'
in the phy driver along with 'depends on PINCTRL_TEGRA'?
