This commit moves the patches for the r8152.c driver to the generic
directory. Previously they were only available on the bcm27xx target.
With these patches the Realtek RTL8153C, RTL8153D, RTL8156A and RTL8156B
chips are supported on all targets by the kmod-usb-net-rtl8152 module.
The RTL8156A and RTL8156B are the 2.5Gb/s Ethernet adapters.
The patches have been tested on TP-Link UE300 (RTL8153A) and UNITEK
1313B (RTL8156B).
