ARM: davinci: board-da830-evm: fix GPIO lookup for MMC/SD
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.
