ARM: dts: imx6sl-warp: Add changes for rev1.12

Warp board rev1.12 is the version of the hardware that will be publicly
available for the customers.

It uses UART5 as the Bluetooth serial port as well as some
additional signals for HOSTWAKE on Wifi and Bluetooth.

Make the changes to support the rev1.12 hardware.
