Assuming the above CONFIG is needed by one of the below
two drivers? Could the above be selected by one of them
in their Kconfig instead of in each defconfig?

The *_r5_defconfigs build both SPL and U-Boot proper, but we only use SPL.
Changing options that only affect U-Boot and not SPL shouldn't be needed.
