MIPS: AR7: Initialize GPIO earlier
In order to detect the Titan variant, we must initialize GPIOs earlier since detection relies on some GPIO values to be set. Signed-off-by: Florian Fainelli <florian@openwrt.org> Patchwork: http://patchwork.linux-mips.org/patch/1562/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org> ---
