ath5k: remove ath5k_hw_get_capability(), don't use VEOL on AR5210
There are only two capabilities we need, and both are trivial to find. ath5k_hw_hasbssidmask() is true on AR5212, but not on AR5210 or AR5211. ath5k_hw_hasveol() is true on AR5211 and AR5212, but not on AR5210, according to the HAL source.
