It requests clock with con-id "fck", if not available, probe fails. Clock for gpmc device with con-id "fck" is created (aliased) along with hwmod device, and for that to happen, main_clk needs to be specified in hwmod entry, add it for OMAP4.

Well, in this case, this is not the preferred way. The hwmod data are supposed to reflect the real HW capabilities. We'd better add the alias in the already existing dummy clock node. Here is the patch to do that.
