wireless: mark prism54 as deprecated and mark for removal

The preferred module is p54pci which also supports FullMAC
PCI / Cardbus devices. We schedule removal for 2.6.34. Reason
to remove this is no one really is testing prism54 anymore,
and while it works p54pci provides support for the same hardware.
It should be noted I have been told some FullMAC devices may not
have worked with the SoftMAC driver but to date we have yet to
recieve a single bug report regarding this. If there are users
out there please let us know!

+What:  PRISM54
+When:  2.6.34
+
+Why:   prism54 FullMAC PCI / Cardbus devices used to be supported only by the
+       prism54 wireless driver. After Intersil stopped selling these
+       devices in preference for the newer more flexible SoftMAC devices
+       a SoftMAC device driver was required and prism54 did not support
+       them. The p54pci driver now exists and has been present in the kernel for
+       a while. This driver supports both SoftMAC devices and FullMAC devices.
+       The main difference between these devices was the amount of memory which
+       could be used for the firmware. The SoftMAC devices support a smaller
+       amount of memory. Because of this the SoftMAC firmware fits into FullMAC
+       devices's memory. p54pci supports not only PCI / Cardbus but also USB
+       and SPI. Since p54pci supports all devices prism54 supports
+       you will have a conflict. I'm not quite sure how distributions are
+       handling this conflict right now. prism54 was kept around due to
+       claims users may experience issues when using the SoftMAC driver.
+       Time has passed users have not reported issues. If you use prism54
+       and for whatever reason you cannot use p54pci please let us know!
