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).
