[media] SoC Camera: add support for g_parm / s_parm operations
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.
