[PATCH] prism54 Bug - Fix frequency reporting

* prism54_get_freq is incorrectly returning channel
* and not frequency. Wireless tools detect this, but
* other programs do not, leading to insane reported
* values. (As Jean documents, drivers should really be
* reporting the frequency).
* An example is wavemon.
