The Topwise A721/LY-F1 tablet is a tablet sold around 2012 under
different brands. The mainboard mentions A721 clearly, so this tablet
is best known under this name.

All 3 nodes above can be replaced with appropriate GPIO_PULL_UP / GPIO_PULL_DOWN
macros inside the *-gpios property.

No need to use pinctrl to configure regular GPIO functions anymore.
