[PATCH] USB: Big endian RTL8150

The RTL8150 USB Ethernet driver doesn't work on big endian machines. Here are
patches (for both 2.4.x and 2.5.x) to fix that. The fix was tested on the
2.4.20 and 2.4.21-rc1 version of the driver on big endian MIPS.

Changes:
  - Fix endianness of rx_creg (from Dimitri Torfs <Dimitri.Torfs@sonycom.com>)
  - Kill unused last parameter of async_set_registers()
