[media] uvcvideo: Fix data type for pan/tilt control 

The pan/tilt absolute control value is signed value. If minimum value
is minus, It will be changed to plus by clamp_t() as commit 64ae9958a6.
([media] uvcvideo: Fix control value clamping for unsigned integer controls).
It leads to wrong setting of the control values. For example,
when min and max are -36000 and 36000, the setting value between of this range
is always 36000. So, its data type should be changed to signed.
