mapphone: call usbhs_omap_remove when modem drops(?)

[MerlijnWajer]

06:31 < tmlind> Wizzup: so the MASTER_USBHOSTHS corresponds to ohci/echi, so usbhshost in                omap4-l4.dtsi, seems that on low battery mdm6600 shuts down, and the usb phy is on the mdm6600 causing invalid access to the phy, or at least that's my guess
06:34 < tmlind> seems like usbhs_omap_remove() or similar should get called to remove the related phys at that point
