camera: prepend ISO mode values with "ISO"

* We can overlay this for AOSP Gallery2 Camera and Focal (and we do),
  but fixing it in the wrapper is better.

Add shutter-speed and iso value to get_parameters so Focal finds them.

This patch adds "shutter-speed" and "iso-value" to the get parameters.
It is needed for ISO and shutter speed setting.

Also it fixes that shutter speed cannot be reset to "auto".

Revert "Use only one set of adreno drivers."

* The 4.3 ones don't work well on a2xx, so we'll use
  what we had from Sony until we get new ones which
  work properly.

This reverts commit bf9958477dfaf66949016c065d7d93f7b0249115.
