From: Alice Guo <alice....@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 v2:
- remove supported boot device type QSPI
- delete unnecessary environment variables
- set "run distro_bootcmd" to be the default boot mode
