Add a list member to gpio_chip that allows all chips to be parsed quickly. The current method requires parsing the entire GPIO integer space, which is painfully slow. Using a list makes many chip operations that involve lookup or parsing faster, and also simplifies the code. It is also necessary to eventually get rid of the global gpio_desc[] array. The list of gpio_chips is always ordered by base GPIO number to ensure chips traversal is done in the right order.
