Lets make the request to get the current noise floor threshold
from the EEPROM band specific as it is band specific, not mode
specific.

This also adds a backpointer on the private channel structure
back to the ieee80211_channel structure as this is now needed during
ath9k_hw_getnf().

HW reset calls pass the same variables or structs
which we can obtain easily from ah. Although this also applies
during channel changes as we will keep around the ath9k_channel
passed as an argument for now.

We now also now propagate the hw reset errors down.

ath_setcurmode() is a bit misleading, all we are doing is

No need to cache when we want to use 2Mbit/s for all protection
frames for 802.11g as we can determine that dynamically on
ath_buf_set_rate() itself.

We don't need to use our own mode for setting the
the routine tries to do, in fact lets remove ath_chan2mode() now as
we can simply use the currently set band and the HT configuration
provided by mac80211 through the ieee80211_conf. This works on
changing channels as well as the internal ath9k_channel we use is
based on the ieee80211_channel in the config.
