[Maverick,linux-firmware] Add link for RTL8192SU firmware

As I was able to test with some hardware in my hands, it seems that
the r8192s_u module will work just fine with the firmware in RTL8192SE.
So adding a simple link makes the hardware work out of the box.
Unfortunately I could not verify whether the same is true for Natty as
that hardware then uses the r8712u module which has its firmware built
into the kernel driver.

Subject: [PATCH] UBUNTU: Add link for RTL8192SU firmware

BugLink: http://bugs.launchpad.net/bugs/721356

Create a link from RTL8192SU -> RTL8192SE as testing proved the same
firmware works for both.

These commits add firmware loading support to r8172u:

The firmware image it uses is "rtlwifi/rtl8712u.bin".

Thanks for the hints. I just did a quick check how we are affected by that. At
the moment those seem to be in linux-next only, so I would not expect this
change to make it into 2.6.38. The firmware file is in the linux-firmware
upstream tree and has made it into the Natty version of linux-firmware. So I
think we should be safe in both cases (in kernel version and newer version
backported by lbm).
