This patch adds support for g_parm / s_parm operations to the SoC Camera
framework. It is usefull for checking/setting camera frame rate.
Example usage can be found in the previous patch from this series,
"SoC Camera: add driver for OV6650 sensor".
Created and tested against linux-2.6.36-rc3 on Amstrad Delta.
Signed-off-by: Janusz Krzysztofik <jkrzy...@tis.icnet.pl>

v1->v2 changes:
- no functional changes,
- refreshed against linux-2.6.36-rc3.
