[PATCH] wireless: Print wiphy name in sysfs.

[greearb@candelatech.com]

From: Ben Greear <greearb@candelatech.com>

The index cannot be used to reliably reconstruct a phy
name, so explicitly add the phy name to sysfs so that scripts
can figure out the parent phy device for a particular
wireless interface.
