From: Alice Guo alice.guo@nxp.com
Supported boot device types in iMX8MM: MMC, DHCP.
CONFIG_CMD_PART is added for command part and CONFIG_CMD_FS_GENERIC is for command fstype.
CONFIG_BOOTCOMMAND which is defined in include/configs/imx8mm_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.

Changes for v3: - add Reviewed-by - re-add boot_fit, initrd_addr and bootm_size which may need to be used Changes for v2: - remove supported boot device type QSPI - delete unnecessary environment variables - set "run distro_bootcmd" to be the default boot mode
