Let ath5k_hw_txpower() decide if it can re-use the powertable or if it has to
be recalculated instead of passing a 'fast' flag from the outside.

Add a new variable to keep track of the currently configured tx power. Before
max_pwr was re-used for keeping the maximum allowed power as well as the
current configuration. Doing a min() on it allows you to lower the txpower, but
how would you be able to make it higher again?
This patch fixes that by adding a new variable ah_cur_pwr which is used instead
of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check
if we are within the limits.
Another problem fixed by this patch is that it avoids setting a zero txpower
when things are initialized first and the current power is not yet set.

Introduce a helper function to get the EEPROM mode from channel and remove
multiple similar switch statements. Also since it's now easy to get the EEPROM
mode from the channel, use them inside the functions which need it, instead of
passing a redundant ee_mode parameter.
