The po1030 read sensor are currently returning the contents of the address+1 fix the probing of the sensor to cope with this. Obviously this needs to be tracked down and fixed.

Currently, we're probing r/w registers at probe time.
This is potentially dangerous, probe some read only registers instead.

s5k83a sensor mounted on many acer laptops have a swiwel allowing it to be rotated. When the camera is in its rotated state, the image needs to be flipped. The only way to check for if the camera has been flipped is to continously poll a register in the m5602. This patch creates a kernel thread which does this. This patch renames some v4l2 ctrls and finally implements a cache in order to prevent unnecessary sensor reads.

Previously all resolution setting was done with precalculated tables.
When the image is vflipped we need to adjust the alignment which would
require another table. Now we can adjust the parameters on the fly instead.
