[PATCH 2/3] arm: mvebu: Espressobin: Use function mmc_get_op_cond() for detecting eMMC

[Pali Rohár]

Use function mmc_get_op_cond() instead of mmc_init() for detecting presence
of eMMC. Documentation for this function says that it could be used to
detect the presence of SD/eMMC when no card detect logic is available.

This function is also used by mx6cuboxi board for detecting presence of eMMC.
