First, again, I don't like moving towards NAND being the default assumed
present storage and making QSPI harder to use.  Second, I forgot about
this earlier but for the record and per later emails, we should just use
CONFIG_CMD_NAND rather than CONFIG_NAND.

We want to keep the default env location to be on the eMMC.

No leading spaces.

Thanks.
