enable CONFIG_CMD_ERASEENV to make it easy to erase env. Use savedefconfig to generate new defconfig.

Not related to this patch, but just curious if imx8qxp-mek also need to export ATF_LOAD_ADDR?
Stil not able to boot imx8qxp-mek with mainline U-Boot.

Not needed. I just updated README, please try. Mostly seco image change in the various releases could cause issue. I am using REV-C1 board, it boots well follow the new README.
