Larry Finger 0529c6b817 rtlwifi: rtl8723ae: Update driver to match 06/28/14 Realtek version
Not only does this patch update the driver to match the latest Realtek release,
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.
