[U-Boot] [PATCH] tao3530: Fix usage of mmc rescan

[Jarkko Nikula]

Currently "bootcmd" does not work as intended but instead prints MMC usage
information and goes directly to "nandboot".

Follow what the commit 669681104daa ("configs: Fix usage of mmc rescan")
does for other boards prior to support for TechNexion TAO3530 SoM was
added.
