i.MX device tree update for 4.20:
 - New board support: Engicam's i.Core MX6 CPU module v1.5; ConnectCore
   6UL Single Board Computer (SBC) Pro; i.MX6 ULZ based EVK board.
 - Add Add SFF interface support for vf610-zii board.
 - Disable unneeded devices like VPU and internal watchdog for imx51-zii
   boards.
 - Add 'no-sdio' and 'no-sd' property for vf610-zii-cfu1 board.
 - Improve i.MX6 SLL GPIO support by adding gpio-ranges property and
   clocks information.
 - Update iomux header for i.MX7 Solo and i.MX6 ULL.
 - Enable GPIO buttons as wakeup source for imx7d-sdb and imx6sx-sdb.
 - Add GPIO keys and egalax touch screen support for imx6qdl-sabreauto.
 - Switch to use SPDX-License-Identifier for more boards - vf610-twr,
   imx7s-warp, Engicam boards.
 - Add device tree bindings of 'fsl,pmic-stby-poweroff' property and add
   the support for i.MX6 RIoTboard.
 - DTC has new checks for SPI buses which will be landed on 4.20.
   A patch from Rob to fix those 100+ warnings on i.MX boards. (Thanks!)
 - Switch i.MX7 device tree to use updated coresight binding for
   hardware ports.
 - Misc small or random update and cleanup.
