ath5k: Update reset code
* Update reset and sync with HALs * Clean up eeprom settings and tweaking of initvals and put them on separate functions * Set/Restore 32KHz ref clk operation * Add some more documentation TODO: Spur mitigation, tpc, half/quarter rate, compression etc v2: Address comments from Bob and Felix and fix RSSI threshold bug introduced on the first version of the patch Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.
