Following 2 hwmod structures are added
    1. usb_host_hs
         The hwmod of usbhs with uhh, ehci and ohci base addresses
         functional clock and ehci, ohci irqs

    2. usb_tll_hs
          hwmod of usbhs with the TLL base address and irq.

Does this really need OCPIF_SWSUP_IDLE?  If so, then there is a hardware 
bug, and some explanation is needed.

The role here doesn't need "usbhost" in its name -- ideally it would be 
something like "120m_fck" or "ehci_logic_fck".

Does this really need OCPIF_SWSUP_IDLE?  If so, then there is a hardware 
bug, and some explanation is needed.

This is missing master, slave, and addr fields.  But see the comment 
below.

Could you describe why there are two struct omap_hwmod_ocp_if records 
here?  It seems to me that these should just be combined into one struct 
omap_hwmod_ocp_if record?  Looking at the clock3xxx_data.c file, the 
usbhost_ick struct clk has l4_ick as its parent, so l4_ick shouldn't need 
to be mentioned explicitly?

Same problem here.  Seems like omap34xx_l4_cfg__usb_tll_hs and 
omap34xx_f_cfg__usb_tll_hs should be combined into one record.

it was not allowing enter usbhs pw domain to enter to low power idle mode; so
I add a comment here.
