The WG7210 document claims that no pulldown/pullup is needed, and we
always had it disabled. The mainline wl1251 driver also reconfigures
that signal to be active high on wl1251 side, and uses rising edge
interrupts (I don't know why it does that).

I think we also need these here:
  OMAP3_WKUP_IOPAD(0x2a54, PIN_INPUT | MUX_MODE4)   /*
reserved.gpio_127 = MMC2_WP */
  OMAP3_WKUP_IOPAD(0x2a56, PIN_INPUT | MUX_MODE4)   /*
reserved.gpio_126 = MMC1_WP */
  OMAP3_WKUP_IOPAD(0x2a58, PIN_OUTPUT | MUX_MODE4)   /*
reserved.gpio_128 = LED_MMC1 */
  OMAP3_WKUP_IOPAD(0x2a5a, PIN_OUTPUT | MUX_MODE4)   /*
reserved.gpio_129 = LED_MMC2 */
