PATCH 1/2 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.

PATCH 2/2 ARM: imx_v6_v7_defconfig: Select HCIUART_H4

The old warp board revision had hardware issues that prevented the RTS/CTS lines to work with the Bluetooth module.

Tha latest rev1.12 fixes this problem, so now we should better use CONFIG_BT_HCIUART_H4 instead, as it provides a better throughput than the CONFIG_BT_HCIUART_3WIRE option.
