There is one cell number missing from the second phandle. It should be:

<&pmx0 0 64 7 &pmx0 7 71 1>;

Otherwise, we will see following error message in kernel boot log when
this GPIO device gets enabled.

There is an indent issue.

If we only want to configure mux mode for a GPIO pin, we do not need to
have a pinctrl group for that, as GPIO subsystem will ask PINCTRL to
set up the mux mode for the GPIO pin being requested, just like how
those LED GPIO pins work on Poplar board.

IMHO, referencing all these pinctrl groups here is not as good as having
client devices reference their pin groups as needed. These "hog" groups
will always request the pins no matter whether corresponding devices is
enabled or not. With client device referencing the phandle, the pins
will only be requested when the device is enabled and probed
successfully. Also, in that case, we can easily find out which devices
use which pins.
