[ Upstream commit 67c6b6ff221f807180aea6dd597246f87e1dd98a ]

The GPIO chip is called davinci_gpio.0 in legacy mode. Fix it, so that
mmc can correctly lookup the wp and cp gpios. Also fix the GPIO numbers
as they are not offsets within a bank.

Note that it is the gpio-davinci driver that sets the gpiochip label to
davinci_gpio.0.
