dm: gpio: uclass: Add flag to control sequence numbering

Like SPI and I2C few GPIO controllers also have multiple chip instances. This patch adds the flag 'DM_UC_FLAG_SEQ_ALIAS' in gpio_uclass driver to control device sequence numbering. By defalut the dev->r_seq for gpio_uclass will alwalys returns -1, which leads the gpio driver probe failure when using the driver with device trees.
