gpiolib: of: Update debug messages for of_get_named_gpiod_flags
Following is the debug output (only a few examples) before and after
the patch.
$ dmesg | grep of_get_named_gpiod_flags
Before:
of_get_named_gpiod_flags: can't parse gpios property
of node '/mmc@12220000[0]'
of_get_named_gpiod_flags exited with status 0
After:
of_get_named_gpiod_flags: can't parse 'wp-gpios' property
of node '/mmc@12220000[0]'
of_get_named_gpiod_flags: parsed 'gpios' property of node
'/gpio-keys/power[0]' - status (0)
