Enable CONFIG_OHCI_HCD_PLATFORM in the ep93xx_defconfig so that USB is still enabled by default on the EP93xx platform.

Manjunath is no longer at Linaro, the email address bounces. Given that, and the fact that others have reported problems with these patches, I'm reverting them until someone from Linaro who can SUPPORT THEM submits them. I will no longer accept patches from linaro.com developers unless a senior Linaro developer has signed off on them, which did not happen with this patch set.

Alan Stern suggested, properly handle ohci-ep93xx suspend scenario. Calling explicitly the ohci_suspend() routine in ohci_hcd_ep93xx_drv_suspend() will ensure proper handling of suspend scenario.

This work is part of enabling multi-platform kernels on ARM.

As Alan Stern pointed out, there is no reason for them to be separate. Also, as Alan Stern suggested, eliminate the ep93xx_start_hc() and ep93xx_stop_hc() routines and simply call clk_enable() and clk_disable() directly. The extra level of redirection does not add any clarity.
