[U-Boot] [PATCH] imx: mx6: fix USB bmode to use reserved value

[Stefan Agner]

From: Stefan Agner <stefan.agner at toradex.com>

Currently the bmode "usb" uses BOOT_CFG1 to 0x01, -which means
BOOT_CFG1[7:4] is set to b0000. According to Table 8-7 Boot
Device Selection this is NOR/OneNAND and not Reserved.

Use 0x10 which leads to b0001, which is a Reserved boot device.
With that the SoC reliably falls back to the serial loader.
