V4L/DVB (6220): TCM825x: Add support for vidioc_int_g_ifparm call, small cleanups

vidioc_int_g_ifparm returns platform-specific information about the
interface settings used by the sensor. Support for [gs]_ext_clk has
been removed.

Fix indentation and remove useless & characters.

Remove experiment for typechecking slave callback function arguments.
