Staging: add rtl8187se driver

This is a driver for the Realtek 8187 "SE" wireless PCI devices in some
netbook computers (MSI Wind, and others).  It includes its own copy of
the ieee80211 stack, but it is compiled into the driver to prevend
duplicate symbol issues.

This version comes from Ralink with no authorship, but it is based
on an old version of the rtl8180 driver from Andrea Merello.  It was
hacked up a bit to get it to build properly within the kernel tree and
to properly handle the merged wireless stack within the driver.
