Subject: [PATCH 3/3] OMAP3 powerdomains: make USBTLL SAR only available on
	ES3.1 and beyond

Richard Woodruff writes that chip errata prevent USBTLL SAR from working
on OMAP3 ES levels before ES3.1:

http://marc.info/?l=linux-arm-kernel&m=123319614808833&w=2

Update the OMAP3 powerdomain structures appropriately.
