Subject: [PATCH] media: iris: implement iris v4l2_ctrl_ops
Initialize the control handler by reading the platform specific firmware
capabilities. Capabilities are features, which are supported by a
specific platform (SOC). Each capability is defined with a min, max,
range and default value and a corresponding HFI. Implement s_ctrl and
g_volatile_ctrl ctrl ops.
