Subject: [PATCH v2] arm: omap: hwmod: make *phy_48m* as the main_clk of ocp2scp

Made *ocp2scp_usb_phy_phy_48m* as the main_clk for ocp2scp.
Since this ocp2scp module does not have any fck but does have a
single opt_clock, it is added as the main_clk for ocp2scp. Also
removed phy_48m as the optional clock since it is now made as the
main clock. By this the driver need not enable/disable phy_48m clk
separately and runtime_get/runtime_put will take care of that.
