pinctrl: bcm2835: Add support for BCM2711 pull-up functionality The BCM2711 has a new way of selecting the pull-up/pull-down setting for a GPIO pin. The registers used for the BCM2835, GP_PUD and GP_PUDCLKn0, are no longer connected. A new set of registers, GP_GPIO_PUP_PDN_CNTRL_REGx must be used. This commit will add a new compatible string "brcm,bcm2711-gpio" and the kernel driver will use it to select which method is used to select pull-up/pull-down. This patch based on a patch by Al Cooper which was intended for the BCM7211. This is a bugfixed and improved version.
