Subject: [PATCH] sunxi: Fix 2nd usb controller on sun4i/sun7i no longer
 working

The 2nd usb controller on sun4i/sun7i has its base address 0x8000
bytes from the 1st one, rather then 0x1000. Also the ahb clk gates
are interleaved with the ohci clk-gates introducing a hole between
the clks for usb1 and usb2.
