brcm47xx: ehci-ssb: some updates:
* update pointers in struct hc_driver * make ssb_ehci_detach more look like the pci version * remove resume and suspend as they are never activated and not compiling * replace ssb_ehci_start with ehci_run as it only calls this method git-svn-id: svn://svn.openwrt.org/openwrt/trunk@21427 3c298f89-4303-0410-b956-a3cf2f4a3e73
