[Buildroot] [PATCH 4/5] board/boundarydevices: add i.MX8MQ support to u-boot scripts

[Gary Bisson <gary.bisson@boundarydevices.com>]

- Update RAM address
- Update kernel image name for ARM64
- Update U-Boot boot command for ARM64
- Remove obsolete cmd_xxx_present check
- Remove obsolete wlan.mac parameter
- Add cmd_mipi command for MIPI-DSI interface
