Subject: [PATCH 1/2] ath5k: more consistent info and error logging

added new macros ATH5K_INFO, ATH5K_WARN and ATH5K_ERR for more consistent
logging inside ath5k. they prepend "ath5k phyX:" to all lines so we can
distinguish between different cards in multi-card setups. ATH5K_WARN and
ATH5K_ERR use net_ratelimit(), so they can be used anywhere without having to
check net_ratelimit() seperately.

the macros get a reference to sc, so we can automatically add additional
information: right now it is used to get the phy name, but having this in one
central place gived us the flexibility to switch to dev_info/warn/... or others
instead too. i think using "phyX" makes the output most readable and easier to
match with the output from mac80211. in cases where we don't have sc available
we still use ATH5K_PRINTF.

changed all printk, most dev_info and most AR5K_PRINTF lines to use these
macros instead. deleted AR5K_PRINT because it's easy to use ATH5K_PRINTF
instead.
