This patch adds GPIO function enable/disable bits for the AR7242, as derived from the D-Link GPL firmware sources for the DIR-632-A1.
Note that of these, AR724X_GPIO_FUNCTION_CLK_OBS6_ENABLE and AR724X_GPIO_FUNCTION_PCIEPHY_TST_EN are explicitly cleared by the D-Link sources. I suspect these bits are necessary to enable the test pin GPIOs although I havent had a chance to scientifically verify this.
