pinctrl: pinconf: separate config parameters with commas for debugfs
To improve debugfs readability, use commas instead of whitespaces
for separating configuration parameters.
For example, the "pinconf-pins" dump on my board will change as follows:
Without this commit:
# head -5 pinconf-pins
Pin config settings per pin
Format: pin (name): configs
pin 0 (ED0): input bias pull down output drive strength (8 mA) input enabled
pin 1 (ED1): input bias pull down output drive strength (8 mA) input enabled
pin 2 (ED2): input bias pull down output drive strength (8 mA) input enabled
With this commit:
# head -5 pinconf-pins
Pin config settings per pin
Format: pin (name): configs
pin 0 (ED0): input bias pull down, output drive strength (8 mA), input enabled
pin 1 (ED1): input bias pull down, output drive strength (8 mA), input enabled
pin 2 (ED2): input bias pull down, output drive strength (8 mA), input enabled
