[PATCH v2] armv8: fsl : create bootcmd and mcinitcmd as per boot source

[Wasim Khan]

From: Wasim Khan <wasim.khan at nxp.com>

NXP platforms expect custom bootcmd and mcinitcmd to be
updated as per boot source with default environment.
Check env variable fsl_bootcmd_mcinitcmd_set to prepare
bootcmd and mcinitcmd

Fixes: cbf77d201870 (armv8: fsl-layerscape: Fix automatic
setting of bootmcd with TF-A)
