604eeadd18 ath5k: add antenna statistics and debugfs file for antenna settings 
keep statistics about which antenna was used for TX and RX. this is used only
for debugging right now, but might have other applications later.

add a new file 'antenna' in debugfs (/sys/kernel/debug/ath5k/phy0/antenna) to show
antenna use statistics and antenna diversity related register values. it can
also be used to set the antenna mode until we have proper support for that in
iw:
  - echo diversity > antenna: use default antenna mode (RX and TX diversity)
  - echo fixed-a > antenna: use fixed antenna A for RX and TX
  - echo fixed-b > antenna: use fixed antenna B for RX and TX
  - echo clear > antenna: reset antenna statistics

31670070ff ath5k: remove permissions from debugfs files 
Don't allow users to open debugfs files, because it can cause oopses.

When a user opens some file, driver unlinks it and frees the
corresponding structure, we will dereference freed memory.
