[PATCH 7/7] aw_gpio: report pinctrl configuration failures

[vice-shore-grid_duck.com]

Summary

A pin or function named by a device tree pinctrl node but absent from the
padconf table was silently ignored, leaving the pin in whatever state the
firmware left it with no trace in dmesg. Print the offending pin and
function, and under bootverbose the mux applied to each pin.

otherwise OK

imho, this is overly verbose.
