The previous patch disables SPL_RAW_IMAGE_SUPPORT for i.MX8M boards
(already disabled for this), this one disables SPL_RAM_DEVICE (was only
enabled for this). Both need to be disabled for this series in its
current form to avoid a binman symbol-related error, but this commit
message suffers from being copy-paste of the previous one.

I don't understand the SPL details much. But I see in spl/spl_ram.c that
CONFIG_SPL_RAM_DEVICE associates BOOT_DEVICE_RAM with a function, and
running 'git grep' for those doesn't turn up anything related to i.MX or
this board. So I guess RAM_DEVICE is actually unused/unusable here and
disabling it won't break anything.
