[U-Boot] [PATCH] embest/mx6boards: only toggle eMMC usdhc3 RST line on MarSboard

[Iain Paton]

On MarS usdhc3 is eMMC, on RIoT usdhc3 is uSD and eMMC is usdhc4.

Don't run the MarS specific eMMC reset code on usdhc3 when 
board_type == BOARD_IS_RIOTBOARD

Digging deeper in patchwork, I found I have not yet applied this old
patch. Sorry for that.
