[PATCH] usbcore: Remove hub_set_power_budget

Browse Source 
This patch removes the hub_set_power_budget routine, which was used by a
couple of HCDs to indicate that the root hub was running on battery power.
In its place is a new field added to struct usb_hcd, which HCDs can set
before the root hub is registered.  Special-case code in the hub driver
knows to look at this field when configuring a root hub.
