ARM: davinci: board-da850-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.
