wavelan: move driver to staging
Move the wavelan driver to drivers/staging. This is another pre-802.11
driver that has seen virtually no non-API-fixup activity in years, and
for which no active hardware is likely to still exist. This driver
represents unnecessary ongoing maintenance for no clear benefit.
This patch brought to you by the "hacking" session at the 2009 Kernel
Summit in Tokyo, Japan...
