I have removed them because, according to the OMAP3430 ES1.0 Revision A 
TRM (SWPU100A), the HS USBHOST subsystem is not present on OMAP3430 ES1.0.  
Therefore the HS USBHOST modules must not be marked as being common to all 
OMAP3xxx chips in the hwmod data.

If you have information that indicates that it's present on OMAP3430 
ES1.0, please let me know ASAP.
