[U-Boot] [PATCH v2 2/4] tegra2: Call gpio_request for SDMMC GPIOs

Without this, the GPIO_CNF register will not be programmed, and hence the
GPIO signals will not reach the pins; the pinmux's configured function
will be routed to the pins instead.

v2: s/SDMMC4/SDMMC3/ in strings passed to gpio_request().
