ath5k: Update RF Buffer handling
* Use the new way to modify rf buffer and put some rf buffer
documentation on rfbufer.h
* Merge all rf regs functions to one
* Sync with legacy HAL and Sam's HAL
* Set gain_F settings so that gain_F optimization engine works
on RF5111/RF5112 (note that both HALs only use step 0 for RF5111
and they don't use gain_F optimization for this chip, code is
there but is never used)
