gpiolib: don't use GPIO global numbers in debugfs output

One of the users of global GPIO numbers in the kernel are the debugfs
callbacks in GPIO drivers. Before converting any custom .dbg_show()
callbacks in individual modules, let's first make GPIO core stop using
GPIO base in debugfs output. Use hardware offsets instead.
