[PATCHv2 8/8] gpio: ppc44x: use dev_name() for chip label

[Rosen Penev <rosenp@gmail.com>]

Replace devm_kasprintf() with dev_name() for the chip label. dev_name()
returns a stable pointer to the device name, so the separate allocation
and -ENOMEM check can be dropped.

Using dev_name() seems to be common for GPIO labels.
