Wire up the GPIO line which Rockchip RK3576 UFS controller uses to reset the connected UFS device. This seems necessary at least for some UFS modules and fixes the following error while enumerating UFS storage: ufshcd-rockchip ufshc@2a2d0000: ufshcd_link_startup: Device not present ufshcd-rockchip ufshc@2a2d0000: link startup failed -6 ufshcd-rockchip ufshc@2a2d0000: ufshcd_pltfrm_init() failed -6 Note that the GPIO descriptor for device resets is already required by the DT binding (link enclosed).
