gpiolib: Document that GPIO line names are not globally unique
gpiochip_set_desc_names() no longer rejects GPIO line name collisions.
Hence GPIO line names are not guaranteed to be globally unique.
In case of multiple GPIO lines with the same name, gpio_name_to_desc()
will return the first match found.
Update the comments for gpio_name_to_desc() and
gpiochip_set_desc_names() to match reality.
Fixes: f881bab038c9667d ("gpio: keep the GPIO line names internal")
