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.

Instead of manually handling the frees use devm. There was also a free
missing in the unregister call which is not needed with devm.
