v3.11-rc1 USB regressions

Hi,

I think USB tree introduced regressions in v3.11-rc1, at least for some
OMAP devices using legacy boot. I have only bisected these; I have no
idea what the real fixes are but the following reverts make Nokia OMAP2+
boards again usable for kernel development work (they need working USB
connection for interacting with the device):

1) USB peripheral mode (g_ether) is broken on Nokia N900, N950 and N9
   (USB_MUSB_OMAP2PLUS). To make it it work, I need to revert three
   commits:

	09fc7d22b024692b2fe8a943b246de1af307132b
	usb: musb: fix incorrect usage of resource pointer
	(Reverting this fixes the g_ether probe failure "couldn't find
	 an available UDC")

	fe4cb0912f8e737f8e4b8b38b9e692f8062f5423
	usb: musb: gadget: remove hcd initialization
	(Reverting this fixes error "cdc_ether: probe of 4-1:1.0 failed
	 with error -110" seen on the host side.)

	8b125df5b24cfb0ec7fa1971e343cc0badc1827d
	usb: musb: eliminate musb_to_hcd	
	(Reverting this fixes compilation error cause by the previous
	 revert.)

2) USB peripheral mode (g_ether) is broken also on Nokia N800 and N810
   (USB_MUSB_TUSB6010). In addition to the above, I need to also revert
   the following:

	b7e2e75a8c6062afe1dd88b0b299938e5d36dff8
	usb: gadget: drop unused USB_GADGET_MUSB_HDRC

   (This commit is clearly incorrect - code checking for this still
   remain in the tree (see e.g. N8x0 board file), so it's not "unused".)
