bcm53xx: use USB patches sent upstream by Hauke
This stabilizes USB support. The old patch was handling initialization in a different order that was causing some problems with few USB 3.0 devices. Some weren't detected, some were working unstable, sometimes USB 3.0 could hang the whole controller. A still known issue (but not a regression) is controller hang triggered by connecting USB 1.1 device when not having OHCI controller enabled (kmod-usb-ohci).
