USB: fix compile problems in ehci-hcd

This patch (as1072) fixes some recently-introduced compile problems
that show up in ehci-hcd when CONFIG_PM is turned off.

	PORT_WAKE_BITS needs to be defined always.

	ehci_port_power() is called during initialization by all the
	EHCI variants other than the PCI version, in which it is
	"defined but not used".  So add a call to it.
