Larry Finger 5c99f04fec rtlwifi: rtl8723be: Update driver to match Realtek release of 06/28/14 
This patch updates the driver to match the latest Realtek release, and
it is an important step in getting the internal code source at Realtek to match
the code in the kernel. The primary reason for this is to make it easier for
Realtek to maintain the kernel source without requiring an intermediate like me.

In this process of merging the two source repositories, there are a lot
of changes in both, and this commit is rather large.
