[PATCH v1 7/9] colibri_imx7: use preboot for fdtfile evaluation

[Igor Opaniuk]

From: Igor Opaniuk <igor.opan...@toradex.com>

Enable and set preboot var with fdtfile evaluation.
preboot will be checked and run immediately before starting the
CONFIG_BOOTDELAY countdown and/or running the auto-boot command resp.
entering interactive mode.

This provides possibility to use different boot cmds in interactive mode
without manual setting fdtfile value, as it it's already evaluated
before entering interactive mode.

Fixes: a62c60610f("colibri_imx7_emmc: add Colibri iMX7D 1GB (eMMC) module 
support")
