This USB/Blackfin commit broke the x86 build with these config options:

 CONFIG_USB_MUSB_HDRC=y
 CONFIG_USB_MUSB_HOST=y
 # CONFIG_USB_MUSB_PERIPHERAL is not set
 # CONFIG_USB_MUSB_OTG is not set
 # CONFIG_USB_GADGET_MUSB_HDRC is not set
 CONFIG_USB_MUSB_HDRC_HCD=y
 CONFIG_MUSB_PIO_ONLY=y
 CONFIG_USB_MUSB_DEBUG=y

Because a side-effect of the patch was that it enabled the driver on x86 
too which doesnt have HAVE_CLK. So this formerly embedded-only driver 
got exposed on the more widely tested x86 platform.

The changelog does not mention this side-effect so i suspect it was 
unintended - so below is the revert of the commit.
