[PATCH v3] imx8mq: configs: add support for distro boot commands

[Alice Guo (OSS) <alice.guo@oss.nxp.com>]

From: Alice Guo <alice.guo@nxp.com>

Supported boot device types in iMX8MQ: MMC, DHCP.

CONFIG_DISTRO_DEFAULTS is added for enabling the DISTRO_DEFAULTS option.

CONFIG_BOOTCOMMAND which is defined in include/configs/imx8mq_evk.h is
deleted because "run distro_bootcmd" is required to be the default boot
mode.

scriptaddr is the location in RAM where boot.scr.uimg/boot.scr will be
loaded to prior to execution.

kernel_addr_r is the location in RAM where the kernel will be loaded to.

Delete unnecessary environment variables because "run distro_bootcmd" is
set to be the default boot mode.

Changes for v3:
 - enable the DISTRO_DEFAULTS option by adding CONFIG_DISTRO_DEFAULTS=y
 - modify commit log
Changes for v2:
 - re-add boot_fdt, initrd_addr and bootm_size which may need to be used
