Add ath5k and ath9k Wifi USB drivers
minor typo fix in rk_camera.c
add GC2035 webcam (Measy U2C) and enable its Volt. reg.
better cpufreq, added 126 MHz freq, set RK1000 in right I2C bus

- On Measy U2C the RK1000 is on I2C bus 2, not on 0, as appears in the
latest kernel.
- I've added a 126 MHz ultra low power mode (used when idle)
- Fixed CPU volatage at 1.6GHz to match TPS' max of 1.4V
- Stable and less restrictive CPU freq. vs temperature regulation
- Added Omegamoon's fix to CPU freq setting (policy->cur = new_rate)
Readded previous RK1000 driver (sound works now, but with a buzz)

The RK1000 sound driver (for Measy U2C headphone jack) did not work at
all in this kernel. I've copied back the previous kernel's driver and
now there is sound again. However, there is also a loud buzzing, still
looking for the cause.
