wl127x/wl128x: add new firmware series as version 5

There are some changes in the newer firmware versions that are not
backwards compatible with older versions of the driver.  Starting on
Linux 3.6, we will need these new versions.

The new versions are X.3.10.2.115 for single-role and X.5.7.0.27 for
multi-role.
