This commit implements frame decimation for stk1160, which allows to support format changes instead of a static frame size. The stk1160 supports independent row and column decimation, in two different modes: * set a number of rows/columns units to skip for each unit sent. * set a number of rows/columns units to send for each unit skipped. This effectively allows to achieve different frame scaling ratios. The unit number can be set to either two row/columns sent/skipped, or four row/columns sent/skipped. Since the video format (UYVY) has 4-bytes, using a unit number of two row/columns results in frame color 'shifting', so set to four row/columns sent/skipped.
