Fix conflict of mounted drives

Fix conflict of SDMMC 0,1 and 2 mount drivers with USB 0 and 1.
Optimization
Try to initialize the eMMC.

The eMMC driver for BBB is not complete, the eMMC is not responding or
something that wil freze the MMCSD1 unit, for this reason I implemented
a timeout that permit to driver to exit with error, and not freezing on
extCSD.
