[OpenWrt-Devel] [PATCH] Support for Edimax EW-7476RPC

Hi Cezary,
In addition to the EW-7476RPC, I added support for the EW-7478AC as you
suggested. I could not test that image, but at least it compiles.
I fixed all of your comments as suggested, however left it at
mediatek,rtl8211e-reset = "yes"; I believe there are other similar
devices from Edimax out there with the Realtek chip, and possibly a
different GPIO line. Then something like mediatek,rtl8211e-reset = <39>;
could be used.
Birger
Here comes the patch:
