imx8mq: configs: add support for distro boot commands
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.
