If, in CONFIG_BOOTCOMMAND, the environment switches both the mmcdev
and bootpart variables to refer to MMC device 1, it would make sense
that the mmcroot env variable should switch to that device as well.

  i asked about this a while back and didn't hear any objections, so
i'll submit it as a patch. as you can see, if the first attempt to run
mmcboot fails, the environment is switched to refer to MMC device 1
(eMMC), and it would seem natural that mmcroot should follow along for
consistency. but i'm willing to be convinced otherwise.
