gpio: pca953x: add more register definitions for pcal953x
PCAL chips ("L" seems to stand for "latched") have additional registers starting at address 0x40 to control the latches, interrupt mask, pull-up and pull down etc. Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
