[PATCH] ARM: i.MX: add barebox,bootsource-mmc aliases

[Sascha Hauer]

Several boards overwrite the standard mmc aliases to give them a board
specific numbering. This breaks our assumption that the bootsource
instance number matches the mmc alias numbering. barebox supports
barebox,bootsource-mmc aliases to provide a mapping between the
bootsource and the device nodes that provides them. Add these aliases
for the newer i.MX SoCs.
