This is a treewide change also updating all users. - Make it possible to take multiple GPIOs in a single hog of device tree hogs. - The refactorings switching GPIO chips to use the .set_config() callback using standard pin control properties and providing a backend into the pin control subsystem that were also merged into the pin control tree naturally appear here too. Testing instrumentation: - A whole slew of cleanups and improvements to the mockup GPIO driver.

New drivers: - New driver for the Cortina Systems Gemini GPIO controller. - New driver for the Exar XR17V352/354/358 chips. - New driver for the ACCES PCI-IDIO-16 PCI GPIO card.

Once the first user is connected to joydev node we'll be updating joydev->abs[] values and subsequent clients will be getting correct initial states as well. This solves issues with joystick driven menus that start scrolling up each time they are started, until the user moves the joystick to generate events. In emulator menu setups where the menu program is restarted every time the game exits, the repeated need to move the joystick to stop the unintended scrolling gets old rather quickly...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Set the LED_CORE_SUSPENDRESUME flag on our LED device so the LED state will be automatically restored by LED core on resume. Since Xbox One pads stop flashing only when reinitialized, we'll send them the initialization packet so they calm down too.
