USB: EHCI: move ehci_update_device() to ehci-lpm.c
In preparation for splitting the ehci-hcd driver into a core library
and separate platform-specific driver modules, this patch (as1618)
moves ehci_update_device() from a couple of platform-specific source
files into ehci-lpm.c. This is where it should have been all along,
since all it does is call a couple of other functions that are already
in ehci-lpm.c.
