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).

+Subject: [PATCH] USB: bcma: remove chip id check
+
+I have never seen any bcma device with an USB host core which was not a
+SoC, the bcma devices have an USB device core with a different core id.
+Some SoC have IDs with 47XX and 53XX in decimal form which would be
+rejected by this check. Instead of fixing this check just remove it.
