pinctrl: core: Show pin numbers for the controllers with base = 0
[ Upstream commitpull/318/head^2482715ff06
] The commitf1b206cf7c
("pinctrl: core: print gpio in pins debugfs file") enabled GPIO pin number and label in debugfs for pin controller. However, it limited that feature to the chips where base is positive number. This, in particular, excluded chips where base is 0 for the historical or backward compatibility reasons. Refactor the code to include the latter as well. Fixes:f1b206cf7c
