[PATCH v1 2/3] ARM: tegra: acer-a500: Add aliases for MMC

[Dmitry Osipenko <digetx@gmail.com>]

MMC core now supports binding to a specific ID, which is very handy for
embedded devices, like Acer A500, because MMC ID may change depending on
kernel version or configuration which affects MMC driver probe order.
