Change Details

The GPIO pins have single corresponding bits in the configuration registers. Hitherto accessor was writing entire word with SYSCON_WRITE_4 instead of doing a proper update with SYSCON_MODIFY_4. Moreover the used mask had incorrect value. Fix both issues and rename the helper routine to gpio_pin_modify. This patch fixes boot with device tree on MacchiatoBin, Armada 7040 DB, Armada 8040 DB and CN913x DB.
