iw: print capability info for DMG (60GHz band)

On the DMG (Directed Multi-Gigabit) aka 60GHz band, capability info
defined by the 802.11ad spec differently from non-DMG one

Detect DMG band by frequency, spec says DMG if above 45 GHz;
parse and print accordingly

For the non-DMG capability info, add more bits as defined in the
IEEE802.11-2012
