mac80211: extend/document powersave API
This modifies hardware flags for powersave to support three different
flags:
* IEEE80211_HW_SUPPORTS_PS - indicates general PS support
* IEEE80211_HW_PS_NULLFUNC_STACK - indicates nullfunc sending in software
* IEEE80211_HW_SUPPORTS_DYNAMIC_PS - indicates dynamic PS on the device
It also adds documentation for all this which explains how to set the
various flags.
Additionally, it fixes a few things:
* a spot where && was used to test flags
* enable CONF_PS only when associated again
