[U-Boot] [PATCH] ARM: exynos5: Try to boot on mmc2 before mmc0/1

[Guillaume GARDET]

As stated in commit a61a4a1db009e3e600258551a01b54c4f50ec103 with DM_MMC,
exynos boards now enumarates external SD/MMC slot as mmc2, instead of mmc1
with legacy mode. Moving mmc2 before mmc1/0 restore the previous behavior 
of trying external SD/MMC before internal slot.
