[U-Boot] [PATCH v1 07/11] DTS: Add imx6q-display5-u-boot.dtsi file with u-boot specific properties

[Peng Fan]

> Subject: [PATCH v1 07/11] DTS: Add imx6q-display5-u-boot.dtsi file with
> u-boot specific properties
> 
> This file setups UART5 based serial to be used as pre-relocation console in the
> U-Boot proper.
> 
> On purpose pinux configuration is omitted here as it has been already done in
> SPL. For early pre-relocation code we only need the serial device from DTS.
