Convert the Renesas R-Car GPIO driver from SIMPLE_DEV_PM_OPS() to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr().

Add a new line-level, boolean property to the gpio-sim configfs interface called 'valid'. It's set by default and the user can unset it to make the line be included in the standard `gpio-reserved-ranges` property when the chip is registered with GPIO core. This allows users to specify which lines should not be available for requesting as GPIOs.

2025-07-04gpiolib: fix performance regression when using gpio_chip_get_multiple()Hugo Villeneuve1-2/+3
commit 74abd086d2ee ("gpiolib: sanitize the return value of gpio_chip::get_multiple()") altered the value returned by gc->get_multiple() in case it is positive (> 0), but failed to return for other cases (<= 0). This may result in the "if (gc->get)" block being executed and thus negates the performance gain that is normally obtained by using gc->get_multiple(). Fix by returning the result of gc->get_multiple() if it is <= 0. Also move the "ret" variable to the scope where it is used, which as an added bonus fixes an indentation error introduced by the aforementioned commit.
